feat(arch): arch_plan_from_spec, three arch_* critique focuses, the arch pack, lean 64 and the counts

The three track-F branches are merged; this is the integration that makes the
twelve SECTION 25 tools one surface.

- engineering/arch/spec.py: a whole plan from one document - walls with their
  openings, stairs, room labels measured off the walls just drawn, the
  exterior chains and the schedules - inside one transaction. Everything the
  model, the wall engine or the stair symbol can refuse is refused before the
  transaction opens, by path; a room point in no closed face rolls it back,
  and so does a cancelled request, under the anyio shield of pid/spec.py.
  EXAMPLE_SPEC's rooms measure 4825 x 5750 and 3825 x 5750 - the net floor,
  computed by hand in the tests.
- engineering/arch/critique.py: arch_room_unlabelled, arch_wall_gap (50 mm,
  one issue per pair of walls, measured to the wall body so an L corner and a
  T stem both read as joined) and arch_opening_clash. One index per critique
  run; a drawing without an ACADMCP_ARCH record yields nothing. Each focus
  has a positive and a negative fixture.
- TOOL_PACK_NAMES gains "arch" (the twelve SECTION 25 tools); lean gains
  arch_wall, arch_opening, arch_room and arch_plan_from_spec and reaches 64;
  the arch tag ranks after mech, so SECTION 25 files as one `architecture`
  group - 241 tools in 26 groups.
- Six golden tuning cases, two of them Turkish, the arch_plan_from_spec alias
  record, the shared-command allowlist reconciled with what the merged records
  claim, the inventory regenerated, the registry snapshot retaken, and the
  README figures taken from check_doc_numbers rather than typed.
- Two more Turkish golden cases close the reconciliation's alias gaps
  ("vaziyet planı çiz" -> arch_plan_from_spec, "oda alanlarını hesapla" ->
  arch_rooms_detect); the arch records carry vaziyet / alan / oda / kat planı
  in diacritic and ASCII-folded spellings, because the search tokenizer splits
  on a non-ASCII letter. BOUNDARY and AREA stay with boundary_trace and
  analysis_measure_entity on purpose, recorded in the arch alias comment.
  Tuning top-1 73/84, top-3 83/84; holdout top-3 15/15.
- tests/test_token_suite.py: TOOL_PACKS=core,mech now drops the arch pack
  too (measured 193 = 236 - 9 - 22 - 12).
