step 4/4: the docs say permissions too, and capability means one thing again

Browse Source 
44 files of prose — CLAUDE.md, AGENTS.md, TODO.md, 20 docs, both plugin design
documents, and the comment surface the earlier steps could not reach.

Applied against an explicit keep-list, not swept, because the word turned out to
have SIX meanings in this repository rather than the three the offscale doc
recorded:

  permissions          renamed (steps 1–2)
  $OFFICER_ROOT/capabilities/  KEPT — the item store, and now the only thing
                               the word means that is ours
  sidecar routing keys renamed to `handles` (step 3)
  Lightning wallet     KEPT — a domain term, and on the wire to the mobile apps
  terminfo queries     KEPT — XTGETTCAP, in the pty sidecar
  InvoiceShelf         KEPT — per-resource { write, bulkDelete } flags

The sweep still falsified two things, both caught by checking rather than by
review, and both in prose that discusses more than one meaning at once:

CLAUDE.md began claiming the item store lives at `$OFFICER_ROOT/permissions`.
It does not; that directory is on disk and full of skills and tools.

And the offscale doc's own note about the collision became
"Named `permissions`, NOT `permissions`" — a sentence that had eaten the thing
it existed to warn about.

Both restored, and the note rewritten to say what is now true: capability means
one thing of ours, and three that belong to somebody else's vocabulary.

Verified live after restart: self and admin permission endpoints 200, gated
route 200, agent-status 200, 9 grants intact with 6 permissions offered.
tsgo clean, 797 tests, 787 pass, same 7.

The rename is done. Four steps, no data lost, no client break that survived
the step it was introduced in.
