refactor: remove dead code and narrow internal exports (knip sweep)

Knip-driven cleanup. All changes verified with tsc --noEmit, lint, and
build.

Removed (zero consumers):
- VERIFICATION_PROMPT constant + its barrel re-export
- createInitialOrchestratorPersistState factory
- transcriptWatcher singleton export
- createAnsiPatternFull / createAnsiPatternSimple factories
- TimerInfo interface + unused AiCheckResult/AiPlanCheckResult imports
  in respawn-controller.ts
- 35 unused Zod z.infer \`*Input\` types in schemas.ts
- Dead re-exports: SessionMode from session.ts, AuthSessionRecord from
  web/ports/index.ts, EnhancedPlanTask/CheckpointReview from
  ralph-tracker.ts, 7 unused entries in utils/index.ts
- 14 event/config interfaces that lived only as JSDoc hints (no TS type
  position usage): Session/Respawn/RalphLoop/RalphTracker/
  SessionManager/SessionAutoOps/Subagent/TaskQueue/TaskTracker/
  TranscriptWatcher/Image/OrchestratorLoop Events + RespawnPreset +
  SessionOutput

Narrowed to module scope (kept but no longer exported):
- buildPermissionArgs in session-cli-builder.ts
- 28 type/interface declarations used only within their own file:
  Ai{Idle,Plan}Check{Config,State}, BashToolParser{Events,Config},
  FileStream/CreateStream{Options,Result}, PlanSubagentEvent,
  SubagentCallback, RalphLoopConfig, RalphLoop{Events,Options},
  ActiveTimerInfo, DetectionStatus, ActionLogEntry, AutoOpsCallbacks,
  TunnelStatus, Timer/LRUMap/StaleExpirationMap Options, AuthState,
  SessionListenerDeps, SseStreamManagerDeps, and 8 more

Docs: CLAUDE.md advice for global-regex `lastIndex` now points to the
remaining `execPattern()` helper instead of the deleted factories.

Knip delta: unused files 42→0, unused exports 161→16, unused types 92→0.
The 16 remaining exports are a mobile-test helper toolkit intentionally
kept for upcoming tests.
