feat: Add rich Claude status animations to FAB

- Add multiple hook-driven animations for FAB (processing, reading, writing, subagent, sessionStart, notification)
- Create claude-status.ts route to handle status updates from Claude Code hooks
- Broadcast status via WebSocket to all connected clients
- Processing (UserPromptSubmit→Stop): orange pulsing dots
- Reading (Read/Glob/Grep): cyan eye icon with scan animation
- Writing (Edit/Write): green pencil icon with pulse
- Subagent: purple orbital ring animation
- SessionStart: green wake-up ripple effect (3s)
- Notification: yellow bounce animation (2s)
- Tool flash: quick white flash on any tool use
