Synchronize restoration facts across authored regions

[hoainho]

Scope

• Initialize restoration state, partial/restored facts, and canonical aliases from authored/canonical world state.
• Keep the canonical five-region set unchanged; persist noncanonical authored-region state locally and migrate legacy boolean-only saves.
• Normalize events, quest consequences, checkpoint restore, save load, and import adoption; preserve safe authored route arrival and renderer tint behavior.
• Document the static authored-collider boundary; no dynamic collision transitions added.

Verification

• npm run typecheck: passed.
• npm run build: passed (existing >500 kB chunk-size warning).
• bun test: 557 passed, 0 failed.
• Renderer browser smoke: PASS; no page errors.
• Native IndexedDB smoke: 19 scenarios PASS; cleanup succeeded. Quota fault is synthetic; gameReady remains false.

Remaining acceptance

This PR addresses restoration state synchronization only. Issue #52 remains open: production runtime/assets and full acceptance are not established, and no restoration-conditioned collider transitions are authored. No production-readiness claim.
