fix: tsc 0 errors + depcruise 0 violations + all GA blockers closed

Changes (37 files, +1159/-587):
- tsconfig: moduleResolution bundler + paths alias for bun:sqlite
- bun-sqlite.ts: type shim replacing stale declare module .d.ts
- All 7 tool files: ToolDefinition alignment (version, output_schema,
  ToolPermissionSpec read_paths/write_paths, ToolCall.call_id)
- 2 adapters: ProviderAdapter implements + ProviderCapabilityMatrix shape
  (provider_kind, enabled, quality_tier, cost_tier, conversion)
- PathClassifier: 9 categories aligned (credential_store, project_air_*)
- CommandRiskAnalyzer: remove unused imports
- Recovery: Database field + scanOrphanReferences FK-off 8 invariants
- Scheduler: rebuild_from_db from session DB tasks
- ProjectionStore: 20+ event types, subscribe, rebuild from repos
- MigrationRunner: constructor accepts optional db_path
- e2e.ts: replaced hardcoded ✅ with 14 real test/check gates
- wiring.ts: eventIngestor.ingest (durable path, INV-2)
- init.ts: ToolRegistry+PermissionEngine path (INV-3)
- TUI: local ProjectionClient (INV-4)
- MainAgent: classify_via_llm with real ProviderManager invocation
- WorkerMessage: kind/session_id/agent_id/correlation_id (contracts §10)
- WorkerProcess exit code 4 = parent_cancelled

Validation gates:
- tsc --noEmit: 0 errors
- depcruise: 0 violations (28 modules)
- tests: 169/169 pass
