gffranco ad1b55a401 backfill: tag commands + file-operations capability
CI / cargo fmt --check (push) Successful in 19s
CI / cargo clippy (push) Successful in 1m11s
CI / cargo test (push) Successful in 1m21s
SPEC audit of Phases 12–13 surfaced two gaps. Closing them here so the
v1.1 command surface and capability advertisement match what §12.3 and
§12.4 promise.

Phase 12 — tag commands (§12.3):
- `nuwiki.tags.search` — case-insensitive substring filter over the
  workspace tag index. Returns `[{ name, uri, range, scope, page }]`
  where `scope` is one of `file` / `heading` / `standalone`.
- `nuwiki.tags.generateLinks` — generates/refreshes a tagged-pages
  section. Two modes:
    - `{ uri, tag }` → `= Tag: <name> =` + flat list of `[[Page]]`
      entries for every page tagged with `<name>`.
    - `{ uri }` (no tag) → `= Tags =` umbrella section with `== <tag>
      ==` subgroups, mirroring `:VimwikiGenerateTagLinks` (no arg).
  Idempotent: re-runs replace the existing section by
  case-insensitive heading match.
- `nuwiki.tags.rebuild` — synchronous full re-walk of the wiki root.
  Drops index entries for pages whose files no longer exist on disk,
  re-parses every `.wiki`, and returns `{ pages, files_seen,
  stale_removed }`. Useful for cleaning up after out-of-band edits
  the LSP didn't see.

Ops layer:
- `tag_hits(index, query) → Vec<TagHit>` — pure filter, sorted by
  (name, page, line).
- `tag_pages_snapshot(index) → BTreeMap<tag, [pages]>` — taken under
  the read lock so the dispatcher can release the lock before
  building the edit.
- `build_tag_links_text` / `tag_links_edit` — text-level rendering
  and the WorkspaceEdit producer.

Phase 13 — file-operations capability (§12.4):
- `ServerCapabilities.workspace.file_operations` now advertises
  `did_rename` + `did_delete` with filters scoped to `**/*.wiki`
  and `**/*.md`. (will_* deferred — those return a WorkspaceEdit
  and we'd want to wire them into the rename pipeline before
  promising support.)
- `did_rename_files` handler — moves the live DocumentState forward
  to the new URI when the file was open, then refreshes the index
  (remove old URI, upsert new via read_or_open).
- `did_delete_files` handler — drops both DocumentState and index
  entry so backlink lookups don't surface dangling source URIs.

Tests: 15 new in `phase17_backfill.rs` covering tag hit filtering &
ordering, snapshot dedup, single-tag and full-index render shapes,
edit replace-vs-insert flow, JSON shape of `TagHit`, and the COMMANDS
list. Total 324 tests pass; fmt + clippy clean.

gffranco e75ad6ca89 phase 16: diary path conventions + nav commands
CI / cargo fmt --check (push) Successful in 27s
CI / cargo clippy (push) Successful in 1m14s
CI / cargo test (push) Successful in 1m20s
Hand-rolled date primitive (no chrono/time dep) plus the diary
command surface that closes the `:VimwikiMakeDiaryNote` ergonomics gap.

nuwiki-core/src/date.rs:
- `DiaryDate { year, month, day }` with strict `YYYY-MM-DD` parsing
  (rejects missing zero-padding, alternate separators, whitespace,
  impossible calendar dates including the leap-year exceptions).
- `next_day` / `prev_day` via Howard Hinnant's days-from-civil
  algorithm — proleptic Gregorian, walks across month/year/leap-day
  boundaries.
- `today_utc()` from `SystemTime::now()`. UTC-only by design: a
  local-tz implementation would need a tz database we don't ship.
- `Ord` by epoch days, `Display`/`format` round-trip with `parse`.

WikiConfig (P15 resolution):
- `diary_rel_path: String` (default `"diary"`) — mirrors vimwiki's
  `g:vimwiki_diary_rel_path`.
- `diary_index: String` (default `"diary"`) — the stem inside the
  diary subdir.
- `diary_dir()`, `diary_index_path()`, `diary_path_for(date)` —
  centralise the path math so commands stay declarative.
- `RawWiki` (init-options wire format) accepts both fields, so users
  with `g:vimwiki_diary_rel_path = "journal"` migrate cleanly.

WorkspaceIndex:
- New `diary_rel_path: Option<String>` field set by `Wiki::new`.
- `IndexedPage.diary_date: Option<DiaryDate>` — populated in `upsert`
  when the URI is under `<root>/<diary_rel_path>/` and the stem
  parses. `diary_date_for_uri` is the standalone classifier.
- The classifier *requires* the URI to be inside the diary subdir
  when a root is known; with no root it accepts any file whose stem
  is a date (kept for the ad-hoc test/scratch case).

nuwiki-lsp/src/diary.rs:
- `uri_for_date` / `index_uri` — bridge from `DiaryDate` and config
  to `file://` URIs.
- `list_entries(index) → Vec<DiaryEntry>` — ascending, plus
  `list_entries_filtered(year, month)` for calendar hooks.
- `next_entry` / `prev_entry` — strict less-than/greater-than
  comparison so navigating from a non-diary page (uses today as
  pivot) still moves to the right entry.
- `build_index_body` — newest-first, grouped under `== YYYY ==` /
  `=== Month ===` subheadings, emits `- [[diary/YYYY-MM-DD]]`. Matches
  `:VimwikiDiaryGenerateLinks`.
- `DiaryEntry` JSON shape: `{ date: "YYYY-MM-DD", uri }`. Manual
  serde impl so DiaryDate stays serde-free in nuwiki-core.

Commands (9 new):
- `nuwiki.diary.openToday` / `openYesterday` / `openTomorrow` →
  `{ uri, date }`.
- `nuwiki.diary.openIndex` → `{ uri }`.
- `nuwiki.diary.generateIndex` → WorkspaceEdit. Three paths:
  live document in `backend.documents` → full-doc replace; on-disk
  index → read + full-doc replace; missing → CreateFile + insert.
- `nuwiki.diary.next` / `prev` → pivots on the current page's
  `diary_date`, falls back to today.
- `nuwiki.diary.listEntries` → optional `year` / `month` filter.
- `nuwiki.diary.openForDate` → strict `YYYY-MM-DD` arg.

All commands accept an optional `uri` to scope to a particular wiki
when multi-wiki lands; the dispatcher falls back to `default_wiki()`.

Tests: 35 new in `phase16_diary.rs` (date parser exhaustively,
calendar arithmetic across boundaries + leaps, path conventions,
upsert classification including the "date filename outside diary dir"
no-op case, list/filter/nav, index body grouping, serde shape, command
list completeness). Total 309 tests pass.

gffranco ce3ac8c4f8 phase 15: link health + TOC/links/orphans
CI / cargo fmt --check (push) Successful in 23s
CI / cargo clippy (push) Successful in 1m29s
CI / cargo test (push) Successful in 1m40s
New diagnostics module hosts the `nuwiki.link` source: walks every
`WikiLinkNode` and emits a diagnostic per broken target. Severity is
gated by `cfg.link_severity` (off | hint | warn | error). Wired into
`collect_diagnostics` so didOpen/didChange publish link diagnostics
alongside parse errors.

Classification (`BrokenLinkKind`):
- `Wiki` target missing from the workspace index → MissingPage.
- `Wiki`/`AnchorOnly` target with an anchor that matches neither a
  heading nor a `:tag:` on the resolved page → MissingAnchor.
- `file:` / `local:` target whose resolved path isn't on disk →
  MissingFile. Absolute paths are used as-is; relative paths resolve
  against the source URI's parent directory, falling back to the wiki
  root.
- Interwiki/Diary/Raw/external — never diagnosed.

`classify_link` works off a `&WikiLinkNode`; `classify_outgoing` does
the same job from a cached `IndexedPage.outgoing` entry so the
workspace-wide checker doesn't need to re-parse every page.

New commands:
- `nuwiki.toc.generate` — generate `= Contents =` heading + nested
  list of `[[#anchor|Title]]` entries from current headings. Replaces
  any existing h1 "Contents" + its immediate following list
  case-insensitively; inserts at line 0 otherwise. Skips the TOC's
  own heading so re-generation is idempotent.
- `nuwiki.links.generate` — equivalent of `:VimwikiGenerateLinks`.
  Flat alphabetical list under `= Generated Links =`, excludes the
  current page.
- `nuwiki.workspace.checkLinks` — returns `Vec<BrokenLinkEntry>` with
  `{ uri, range, kind, message }` per broken link across the wiki.
  Open documents use live text for range conversion; closed pages
  fall back to the stored span coords. Accepts an optional `uri` to
  pick a specific wiki; defaults to the first registered one.
- `nuwiki.workspace.findOrphans` — returns `Vec<{ uri, name }>` for
  every indexed page with no incoming links. Sorted alphabetically.

Pure ops (`commands::ops`):
- `build_toc_text(items, heading_name)` — formats the TOC body with
  2-space indent per level, anchors via `index::slugify`.
- `build_links_text(pages, heading_name, exclude)` — formats the flat
  list.
- `find_section_range(ast, heading_name)` — locates an existing h1
  section (heading + immediate following list) by case-insensitive
  title match.
- `toc_edit` / `links_edit` — full edit producers.
- `collect_workspace_broken_links` / `find_orphans`.

Plumbing:
- `collect_diagnostics` gains a `uri: Option<&Url>` parameter so
  link-health can resolve `file:` / `local:` relatives. `ast_diagnostics`
  back-compat wrapper preserved.
- `Backend::default_wiki` is no longer `#[allow(dead_code)]`.

Tests: 31 new in `phase15_link_health.rs` covering severity mapping,
classification on every kind/anchor case, TOC nesting, links exclusion,
section-range case-insensitivity, idempotent re-generation, orphan
detection, and the COMMANDS list. The Phase 11 stub test was rewritten
into a real "no index = no diagnostics" assertion. All 274 tests pass.

gffranco f1d046fad1 phase 14: list/heading edit commands + CommandOutcome split
CI / cargo fmt --check (push) Successful in 20s
CI / cargo clippy (push) Successful in 1m11s
CI / cargo test (push) Successful in 1m11s
Six new executeCommand entries — the cheap surgical edits that account
for the bulk of vimwiki users' daily keymap traffic. Heavier commands
(table.align/moveColumn/insert, list.changeSymbol/changeLevel/renumber/
removeDone, link.normalize, colorize) are deferred for a follow-up
since each needs its own structural rewriter.

CommandOutcome split:
- `Edit(WorkspaceEdit)` — server applies via apply_edit.
- `Value(Value)` — returned verbatim to the client (used by
  read-only queries like nextTask).
- execute_command handler in lib.rs dispatches both cases.

New commands:
- nuwiki.list.toggleCheckbox — [ ] ↔ [X]; mid-states snap to [X];
  rejected reverts to [ ].
- nuwiki.list.cycleCheckbox — [ ] → [.] → [o] → [O] → [X] → [ ];
  rejected resets to [ ].
- nuwiki.list.rejectCheckbox — toggle the [-] rejected marker.
- nuwiki.list.nextTask — returns Location of the first unfinished
  task after the cursor; wraps to the start of the doc when none
  found below. Only items with checkboxes count.
- nuwiki.heading.addLevel — = → ==; clamps at 6.
- nuwiki.heading.removeLevel — == → =; clamps at 1 (no-op on h1).

Pure ops:
- ops::toggle_state / cycle_state / reject_state — checkbox state
  transitions.
- ops::checkbox_edit / next_task / heading_change_level —
  end-to-end edit producers. Tests drive these directly without
  spinning up a Backend.
- ops::rewrite_heading_with_level — text-level rewrite preserving
  the leading whitespace that marks a centered heading (lives
  outside the heading span, so the edit doesn't touch it).
- ops::find_list_item_at / find_checkbox_span / item_in_list —
  AST + source-text helpers, pub for downstream tooling.

Tests (21 new):
- State transitions: round-trip, progression, dash toggle.
- checkbox_edit: empty → done, partial → cycle, reject path,
  no-op on plain item, no-op off list, nested-sublist resolution.
- heading_change_level: h2→h3, level-6 cap, h3→h2, h1 no-op,
  off-heading no-op, span boundary semantics.
- next_task: first-unfinished, wrap-around, all-done returns
  None, plain items ignored.
- COMMANDS list ↔ handler match.

All 211 prior tests still pass.

gffranco cb4bfae5e7 phase 13: workspace/rename + executeCommand router + nuwiki.file.delete
CI / cargo fmt --check (push) Successful in 29s
CI / cargo clippy (push) Successful in 1m15s
CI / cargo test (push) Successful in 1m15s
Server-side rename with cross-document link rewriting (P11's
read_or_open delivers on its promise) and the first executeCommand
entry. Plus the routing infrastructure that Phases 14-17 will hang
their own commands off of.

commands.rs:
- commands::execute(backend, name, args) dispatches by command name
  and returns the WorkspaceEdit to apply.
- COMMANDS const slice is the source of truth for what's advertised
  in ExecuteCommandOptions.commands.
- First entry: nuwiki.file.delete with args { uri: <Url> } returning
  a WorkspaceEdit with a DeleteFile op.

rename.rs:
- compute_rename(backend, target_uri, new_name, utf8):
  1. Resolve the wiki via wiki_for_uri.
  2. Build new URI from wiki.root + new_name + extension.
  3. Snapshot the index's backlinks for the old page name before
     releasing the read lock so we don't hold it across awaits.
  4. For each backlink, read_or_open the source (live state or
     disk + reparse) and validate the cached span against current
     text.
  5. Rewrite the [[...]] segment with rewrite_wikilink_target,
     preserving anchor and description.
  6. Add the RenameFile op so the builder emits it before the text
     edits in documentChanges ordering.
- build_new_uri handles subdirectory paths and avoids double-
  appending the file extension.
- rewrite_wikilink_target is pub so other tooling can call it.

lib.rs:
- Capabilities: rename_provider + execute_command_provider listing
  commands::COMMANDS.
- New rename handler: cursor-on-wikilink renames the linked page,
  else the buffer's file. Delegates to rename::compute_rename.
- New execute_command handler dispatches via commands::execute, then
  pushes the resulting WorkspaceEdit through client.apply_edit. On
  unknown command or bad args, logs and returns null.
- read_or_open loses its allow(dead_code) attribute now that Phase
  13 calls it.
- rename_target_uri helper shares index-resolution with goto_def.

Tests (11 new in phase13_rename_commands.rs):
- rewrite_wikilink_target: plain, with description, with anchor,
  with both, subdirectory path, non-wikilink-text rejection.
- build_new_uri: under root, with subdirectory, extension dedup,
  empty path segments skipped.
- nuwiki.file.delete builder smoke test (DocumentChanges + DeleteFile).

All 211 v1.0+Phase 11+12 tests still pass.
