## What changed
- Add a configurable `agents.resume` action, bound to `Ctrl+O` by default, that opens the session resume picker from the agent command center.
- Preserve command-center state when the picker is cancelled, and preserve per-thread composer and queued-input state when switching sessions.
- Keep resume failures within the command-center flow and wrap footer shortcuts on narrow terminals.
## Testing
- Add coverage for picker cancellation, active-session selection, resume failures, per-thread input restoration, custom keybindings, and narrow footer layout.
