feat: enable C&C, compact mise tasks, update docs

- Cherry-pick C&C support (ntfy poller for commands, response handling)
- Compact mise.toml with native dependency chaining
- Update AGENTS.md with C&C documentation
- Update README.md with display modes and C&C usage

 ## Git Hooks

 - **ntfy.py** and **mic.py** are standalone modules with zero internal dependencies
 - **eventbus.py** provides thread-safe event publishing for decoupled communication
-- **controller.py** coordinates ntfy/mic monitoring
+- **controller.py** coordinates ntfy/mic monitoring and event publishing
+- **effects/** - plugin architecture with performance monitoring
 - The render pipeline: fetch → render → effects → scroll → terminal output
+
+### Display System
+
 - **Display abstraction** (`engine/display.py`): swap display backends via the Display protocol
   - `TerminalDisplay` - ANSI terminal output
   - `WebSocketDisplay` - broadcasts to web clients via WebSocket
   - `MultiDisplay` - forwards to multiple displays simultaneously
+
 - **WebSocket display** (`engine/websocket_display.py`): real-time frame broadcasting to web browsers
   - WebSocket server on port 8765
   - HTTP server on port 8766 (serves HTML client)
   - Client at `client/index.html` with ANSI color parsing and fullscreen support
+
+### Command & Control
+
+- C&C uses separate ntfy topics for commands and responses
+- `NTFY_CC_CMD_TOPIC` - commands from cmdline.py
+- `NTFY_CC_RESP_TOPIC` - responses back to cmdline.py
+- Effects controller handles `/effects` commands (list, on/off, intensity, reorder, stats)
