feat: Add transcript-debug page with multi-agent support, hooks approval, and message selection

- Transcript debug: JSONL viewer, parsed chat view, realtime WebSocket updates, session selector
- Multi-agent: ejecutor, nucleo000, and claude (global ~/.claude/projects/) with agent switcher
- Hooks approval: permission/plan request forwarding via PowerShell hooks, long-poll API, UI modals
- Chat features: session ID copy, select mode with checkboxes, multi-select copy, select all/deselect all
- File watchers for all agent transcript directories with polling fallback on Windows
