docs: refresh ARCHITECTURE + CLAUDE with this session's work

- Pattern #2 (useNitroQuery): list the eight catalog-layer queries
  carved out of useCatalog this session (gift / groups / club offers /
  pet palette / marketplace / club gifts), plus the new
  useNitroEventInvalidator companion for server-push refresh.
- Note ICatalogOptions deleted — the legacy 'catalogOptions' bag has
  no remaining fields after the migrations, useCatalog no longer
  exposes it.
- New 'useCatalog decomposition (in progress)' table — what's been
  lifted to TanStack and what's deferred (page tree + Builders Club
  status, both core state slices that move with the data/actions
  split).
- Pattern #4 (god-hook split): add the three new splits done this
  session (chat-input doorbell-style, wired-tools singleton-filter,
  translation singleton-filter inline).
- Bump Vitest count 83 → 99 (added 16 cases on the
  useCatalogFavorites helpers).
- Note the pure-module test convention: import from concrete file
  paths rather than the api barrel to avoid jsdom pulling in Pixi.
- Typecheck baseline: client now reports 0 too (was 57 at last
  doc-write); the section's enumerated sweeps all landed.
- CLAUDE.md: bump '77/77' references to '99/99' (both places).

   mutate internal state, document the reason in the commit message and
