docs(gap): record re-audit findings (3 new command gaps + 3 refinements)

Three parallel audits (commands/mappings/configs) re-verified all recent fixes
PASS across every context and surfaced new command-attribute gaps, each
confirmed against the code:

New P3 command gaps:
- VimwikiChangeSymbolTo / VimwikiListChangeSymbolI lack -range (upstream has it)
  → E481 on a visual selection.
- VimwikiGenerateLinks lacks -nargs=? (upstream optional rel-path arg) → E488.
- NuwikiGenerateTags missing (Vimwiki form + NuwikiGenerateTagLinks exist) —
  :Vimwiki*↔:Nuwiki* asymmetry.

Refinements to existing P3 items:
- TableAlignQ/W: also bare vs upstream -nargs=? (E488 with an arg).
- VimwikiSearch/VWS: also -nargs=1 vs upstream -nargs=*.
- diary -count: VimwikiDiaryIndex is an additional instance to fold in.
- color_dic: note the empty-default vs upstream-palette divergence (doc-accurate,
  not a doc↔code mismatch) next to color_tag_template.

Mappings + configs audits: clean — no new gaps, all recent work consistent,
subgroup descriptions match code. Tally now 30 done / 27 open (all P3).
