Resolves the 18 findings from the parallel codebase review, tracked in development/vimwiki-gap.md. Correctness / perf: - Wiki.config -> Arc<WikiConfig> so cloning a Wiki is a refcount bump (R5) - WorkspaceIndex::remove is no longer O(n^2): a per-source contributions map limits the scan to buckets the source actually wrote into (R6) - render_color now expands color_tag_template (__STYLE__/__CONTENT__), consuming the previously-dead field; ColorNode documented as an extension point; 3 renderer tests added (R3/R4) - wiki_root_for returns empty/nil on no-match instead of falling back to the first wiki (R2); auto_header honours links_space_char (R7) Cleanup / dedup: - Remove dead #[allow(dead_code)] stubs + uncalled pub helpers, narrow imports (R10/R11) - Dedup span_of_inline x3 -> InlineNode::span() (R12) - diary_step single read lock; page_captions single pass (R13) - Lua auto_header loop -> wiki_list(); detect_current_symbol cleanup (R14/R18) Client / docs: - :VimwikiNormalizeLink Vim cmds -> <q-args> (R17); ftplugin header fix (R16); vars.vim multi-wiki limitation documented (R15) - Document 19 config options in README.md + doc/nuwiki.txt; fix list_margin/shiftwidth doc and stale comments (R1/R9) - R8 investigated, confirmed not a real bug (documented) Verified: Neovim harness 307, Vim harness 301/18/21, Rust suite 568, all 0 failed; clippy clean; fresh parallel-agent audit found no regressions.
