phase 11: plumbing prereqs — Wiki, edits, config, snapshot, diags
Cross-cutting infrastructure that every v1.1 phase depends on. Lands as
a numbered phase before any user-visible feature so Phases 12–19 stay
mechanical.

5 pieces:

- `config.rs` — `Config` + `WikiConfig` + `DiagnosticConfig` + `LinkSeverity`.
  Serde-deserialised from `initialization_options`. v1.0 single-wiki
  shape (`wiki_root` + `file_extension` + `syntax`) desugars to one-entry
  `wikis = [...]` per P16. `~/...` expansion without pulling in `dirs`.
  Fallbacks: workspace_folders[0] → deprecated root_uri → empty list.

- `wiki.rs` — `Wiki` aggregate (id + WikiConfig + Arc<RwLock<Index>>).
  `build_wikis(&[WikiConfig])` materialises the list; `resolve_uri_to_wiki`
  picks the longest-prefix root match so nested wikis route correctly.
  Single-entry today, multi-entry once Phase 18 lands.

- `edits.rs` — `WorkspaceEditBuilder` + `text_edit_replace/insert/delete`
  + `op_rename/delete/create`. Handles the UTF-8/UTF-16 conversion at the
  span boundary so each Phase 13+ command stays a 3-liner. Builder picks
  `documentChanges` when file ops are present (LSP requires it), `changes`
  map otherwise (works for LSP 3.15- clients). File ops precede content
  edits in the output so created/renamed files exist when edits apply.
  `DeleteFile` is built without `annotation_id` — lsp-types 0.94.x ships
  it that way; later versions added the field.

- `Backend` refactor — `index: Arc<RwLock<WorkspaceIndex>>` replaced by
  `wikis: Arc<RwLock<Vec<Wiki>>>` + `config: Arc<RwLock<Config>>`. New
  `wiki(id)` / `default_wiki()` / `wiki_for_uri(uri)` helpers. Every v1.0
  handler (definition, references, hover, completion, workspace/symbol,
  update_document) goes through `wiki_for_uri`. `initialize` builds wikis
  from `Config::from_init_params`; `initialized` spawns one indexer task
  per wiki with the existing `window/workDoneProgress` wrapper. New
  `did_change_configuration` handler re-applies settings (rebuild
  semantics revisited in Phase 18). The old `workspace_root_from_params`
  helper is gone.

- `read_or_open` + `DocSnapshot` (scaffolded, `#[allow(dead_code)]` until
  Phase 13's `workspace/rename` consumes it). Returns the live document
  when held in the documents map, otherwise async-reads from disk and
  re-parses so cross-document operations get accurate text and spans
  instead of trusting stale `WorkspaceIndex` data.

- `collect_diagnostics` composable collector. Same `ErrorNode` walk
  today; takes `Option<&WorkspaceIndex>` + `page_name` + `&DiagnosticConfig`
  so Phase 15 can drop a link-health source in without further refactor.
  `ast_diagnostics` kept as a thin wrapper for the v1.0 test surface.

New deps: `serde` + `serde_json` (already transitive through tower-lsp;
elevated to direct deps for clarity and stability). `tokio` gains the
`fs` feature for `read_or_open`'s async disk read.

Tests (19 new in `phase11_plumbing.rs`):
- Edits: UTF-8 passthrough + UTF-16 conversion (`héllo`), insert/delete
  shape, builder mode selection, file-op accumulation, `op_create` round-trip
- Config: defaults, v1.0 desugar, explicit list overrides legacy, empty
  JSON, invalid JSON preserves prior state
- Wiki: sequential id assignment, longest-prefix resolution, no-match,
  `Wiki::contains`
- Diagnostics: error-node composition, link-health stub returns empty in
  Phase 11

All 172 v1.0 tests still pass — backward compatible.

# nuwiki
A Vim/Neovim plugin providing full vimwiki syntax support, implemented as a
Rust-based language server (LSP).
> **Status:** v1.0 (Phases 010) shipped — parsing, highlighting, navigation,
> editor glue, and release pipeline are all live. v1.1 (Phases 1119) in
> progress, closing the gap to a full vimwiki replacement: tags, diary,
> server-side edit commands, link health, HTML export commands, multi-wiki,
> and the `:Vimwiki*` keymap layer.
See [`SPEC.md`](./SPEC.md) for the full project specification.
