data(content): core architecture-flavor trait-template catalog (#1005)

The D-232 core hand-curated catalog (28 templates) the architecture-flavor
draw reads from, baked into trait_templates (#993):

- Cross-corridor pool (10): economic-function templates gated by BulkClass
  (extraction/industrial/cold-chain/precision/information/civic) + universal
  baselines + the foreign-import swerve. Guarantees the CI floor.
- Per-corridor baseline (8): each corridor's default cohesive look — core
  cosmopolitan, north anglo-frontier, south lusophone, west germanic +
  compact-cooperative, east dense-utilitarian, deep-frontier surname +
  hardscrabble.
- Heritage sub-pools (10): deep-history callbacks tied to the D-237 heritage
  taxonomy (scottish highland, west-african compound, iberian hacienda,
  atlantic creole, nordic timber, central-european blok, east-asian temple,
  vietnamese water village, afrikaans kraal, arab oasis).

Each template = holistic bundle: two-tier eligibility (hard gates
bulk_class/ubiquity/prosperity_bps + soft weight mods), zone_affinity over
the real DistrictType enum, allow/block tags from a shared ObjectTag
palette, and a D-235 visual_bundle with generic fallback parents. All
numerics integer basis-points (D-010).

Adds the D-232 CI guardrails to the baker (V-TT-01: >=5 templates eligible
per BulkClass; V-TT-02: no template >60% of pool weight) — both pass with
margin (23-24 eligible/class, 5% max share). Catalog can grow via the
bounded Gemma pass (#992); hero pins are #1017.
