feat(story-115): hot-reload project.toml agent config without server restart

Browse Source 
- Extend `WatcherEvent` to an enum with `WorkItem` and `ConfigChanged` variants
  so the watcher can distinguish between pipeline-file changes and config changes
- Watch `.story_kit/project.toml` at the project root (ignoring worktree copies)
  and broadcast `WatcherEvent::ConfigChanged` on modification
- Forward `agent_config_changed` WebSocket message to connected clients; skip
  pipeline state refresh for config-only events
- Add `is_config_file()` helper with unit tests covering root vs. worktree paths
- Accept `configVersion` prop in `AgentPanel` and re-fetch the agent roster
  whenever it increments
- Increment `agentConfigVersion` in `Chat` on receipt of `agent_config_changed`
  WS event via new `onAgentConfigChanged` handler in `ChatWebSocket`
