feat: 远程群控 (#243)

* feat: restore pipe IPC, LAN pipes, monitor tool, and PR-package features

Core IPC system (UDS_INBOX):
- PipeServer/PipeClient with UDS + TCP dual transport, NDJSON protocol
- PipeRegistry: machineId-based role assignment, file locking
- Master/slave attach, prompt relay, permission forwarding
- Heartbeat lifecycle with parallel isPipeAlive probes
- Commands: /pipes, /attach, /detach, /send, /claim-main, /pipe-status

LAN Pipes (LAN_PIPES):
- UDP multicast beacon (224.0.71.67:7101) for zero-config LAN discovery
- PipeServer TCP listener, PipeClient TCP connect mode
- Heartbeat auto-attaches LAN peers via TCP
- Cross-machine attach allowed regardless of role
- /pipes shows [LAN] peers with role + hostname/IP
- SendMessageTool supports tcp: scheme with user consent

Architecture — extracted hooks from REPL.tsx (~830 lines → ~20 lines):
- usePipeIpc: lifecycle (bootstrap, handlers, heartbeat, cleanup)
- usePipeRelay: slave→master message relay via module singleton
- usePipePermissionForward: permission request/cancel forwarding
- usePipeRouter: selected pipe input routing with role+IP labels
- Shared ndjsonFramer.ts replaces 3 duplicate NDJSON parsers

Key fixes applied during development:
- Multicast binds to correct LAN interface (not WSL/Docker)
- Beacon ref stored as module singleton (not Zustand state mutation)
- Heartbeat preserves LAN peers in discoveredPipes and selectedPipes
- Disconnect handler calls removeSlaveClient (fixes listener leak)
- cleanupStaleEntries probes without lock, writes briefly under lock
- getMachineId uses async execFile (not blocking execSync)
- globalThis.__pipeSendToMaster replaced with setPipeRelay singleton
- M key only toggles route mode when selector panel is expanded
- User prompt displayed in message list on pipe broadcast
- Broadcast notifications show [role] + hostname/IP for LAN peers

Other restored features:
- Monitor tool: /monitor command, MonitorTool, MonitorMcpTask lifecycle
- Daemon supervisor and remoteControlServer command
- Tools: SnipTool, SleepTool, ListPeersTool, SendUserFileTool,
  WebBrowserTool, WorkflowTool, and 10+ stub→implementation rewrites
- Feature flags: UDS_INBOX, LAN_PIPES, MONITOR_TOOL, FORK_SUBAGENT,
  KAIROS, COORDINATOR_MODE, WORKFLOW_SCRIPTS, HISTORY_SNIP

Tests: 2190 pass / 0 fail (15 new: lanBeacon 7, peerAddress 8)

* fix: resolve merge conflicts and fix all tsc/test errors after main merge

- Export ToolResultBlockParam from Tool.ts (14 tool files fixed)
- Migrate ink imports from ../../ink.js to @anthropic/ink (7 files)
- Fix toolUseID → toolUseId typo in monitor.ts and MonitorTool.tsx
- Add fallback values for string|undefined type errors (8 locations)
- Fix AppState type in assistant.ts, add NewInstallWizard stubs
- Fix ParsedRepository.repo → .name in subscribe-pr.ts
- Fix AgentId/string type mismatch in BackgroundTasksDialog.tsx
- Fix PipeRelayFn return type in pipePermissionRelay.ts
- Use PipeMessage type in usePipeRelay.ts
- Fix lanBeacon.test.ts mock type assertions
- Create missing MouseActionEvent class for ink package
- Use ansi: color format instead of bare "green"/"red"
- Resolve theme.permission access via getTheme()

Result: 0 tsc errors, 2496 tests pass, 0 fail
