docs(gap): re-audit — confirm recent fixes, log new gaps

Re-audited config / mappings / commands against vimwiki master with three
parallel agents. All recent P1/P2/P3 work confirmed present and correct in
both clients (no regressions). Logged new gaps the pass surfaced:

- P3 commands: diary-note family lacks -count (upstream -count=0); no
  -complete= specs (page/tag/colour command-line completion); minor attribute
  gaps (NormalizeLink -nargs=?, CheckLinks -range, Colorize -nargs=* vs 1).
- P3 mappings: <D-CR> (macOS Cmd+Return) tab-drop alias missing in both
  clients; <Leader>w<Leader>m absent from the Vim *global* map block in
  plugin/nuwiki.vim (present buffer-locally).
- Intentional divergences: global_ext (always-on via ftdetect) and the
  syntax-default name (vimwiki vs default) noted so future audits skip them.

+- [ ] **No `-complete=` specs** _(new)_ — upstream attaches command-line completion
