feat: Resources & Industry — per-region resource profiles + industry LLM lever (v0.36.0, #59)

- scripts/build-region-resources.mjs: deterministic, idempotent builder →
  public/region-resources.json (1,800 entries; FNV-1a hash × area factor, 0–1, 2dp)
- server/regions.ts: hasResources()/resourceOf() optional-manifest loader
- shared/types.ts: RegionResources, IndustryType/INDUSTRY_TYPES, IndustryProject,
  GameState.industry
- shared/protocol.ts: IndustryOps, TurnResult.industry, deriveNationResources
  (area×population-weighted average, 2dp)
- server/engine.ts: isIndustryType, validateIndustryOps, applyIndustryOps
  (per-region SET, first-declared-type wins), applyIndustryEffects
  (INDUSTRY_ECONOMY_BONUS=1, +1 when region industry≥0.5; sole-owner only;
  0/2+ owner regions kept but no boost; re-derive after), system+user prompt
  contract lines, runTurn resourceOf opt, nationResources in user payload
- server/db.ts: legacy-row industry default migration
- server/stub.ts: industry:{projects:[]} in stub result; resources/industry
  in StubPayload (never read)
- server/index.ts: resourceOf wired to jump route
- All test fixtures updated; new describe blocks in engine.test.ts,
  protocol.test.ts, regions.test.ts, db.test.ts
- CHANGELOG.md v0.36.0, AGENTS.md docs, package.json 0.36.0

Fixes #59
