refactor: remove dead notification systems and legacy broadcasts

- Delete claude-hooks.ts store (processHook never called, always empty)
- Delete HookNotifications.vue and NotificationLog.vue (orphan components)
- Delete claude-status.ts route and broadcastClaudeStatus (no consumers)
- Delete agent-bar.md legacy doc
- Remove legacy WS 'claude-hook' broadcast (frontend ignores it)
- Move isAgentRunning tracking into broadcastClaudeHook
