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

+- **Resources & Industry — per-region resource profiles + the `industry` lever (v0.36, #59).**
+  Since v0.36 each of the 1,800 sub-regions carries a **synthesized 4-value resource profile**
+  (`{ oil, iron, food, industry }`, each 0–1, 2dp) from the committed `public/region-resources.json`
+  — built by the deterministic, idempotent `scripts/build-region-resources.mjs` (an FNV-1a hash of
+  `` `${key}\u0000${resource}` `` scaled by an area factor from `region-geo.json`, clamped to 1,
+  byte-identical re-run) and loaded by `server/regions.ts` via the same optional-manifest pattern as
+  the other manifests (`hasResources()` / `resourceOf()`, probe `public/` then `dist/`; a missing or
+  malformed file degrades — boosts use the unscaled base value and the aggregate is omitted from the
+  prompt, never a crash). `TurnResult.industry = { projects: IndustryProject[] }` (required, default
+  `{ projects: [] }`; `IndustryProject = { regionKey, type }`, `type ∈ INDUSTRY_TYPES =
+  oil | iron | food | industry`) declares a project on a region. `applyTurnResult` maintains
+  `GameState.industry` (required, `[]` at creation; a legacy SQLite row without the field loads as
+  `[]` — `db.ts`, additive, never wiped) as a **per-region SET**: a region key not in the valid-keys
+  manifest is dropped; a region that already hosts a project is untouched (the first declared type
+  wins — re-declaring is a no-op, the type is never replaced). Every committed turn,
+  `applyIndustryEffects` (placed after the economy block, before markers; the owner is resolved from
+  the FINAL post-claim ownership) grants each active project's region's **SOLE owner** a small,
+  deterministic economy boost — `INDUSTRY_ECONOMY_BONUS = 1` plus one extra point when the region's
+  `industry` resource value is ≥ 0.5 (without the manifest, just the base) — clamped to 0–100,
+  mirrored to every region the owner holds (`regionStats`), and each affected nation's derived `stats`
+  re-derived afterwards (same 0-region / no-entry guards as the economy/hybrid dips). A project on a
+  region with 0 or 2+ owners yields no boost but is **kept** in the list (never removed, never
+  thrown); sole ownership is untouched (the layer moves stats, never territory). `isMeaningful`
+  counts non-empty `industry.projects`; the system prompt documents the field + constraints (a region
+  holds at most one project — never re-declare on a region that already has one; at most 1–2 per
+  turn, each narrated in `events`), and the user payload carries the active projects (`industry`)
+  plus each nation's aggregate resource profile (`resources` — `deriveNationResources` in
+  `shared/protocol.ts`, the area×population-weighted **average** of the owned regions' profiles;
+  omitted entirely when the manifest is not loaded). The **stub never** declares a project
+  (`industry: { projects: [] }`) — e2e (CI, `LLM_STUB=1`) is unaffected and the path is unit-tested
+  only (`server/engine.test.ts`, `server/protocol.test.ts`, `server/regions.test.ts`,
+  `server/db.test.ts`, `scripts/build-region-resources.test.ts`).

   Clicking a sub-region does NOT open a popup — it switches the dossier to that sub-region's
