## Why
The command center's shortcut footer consumes several rows in narrow terminals, leaving less space for tasks. The overview also ignores attempts to dismiss it with `Esc`.
## What changed
- Keep primary actions in a single-line footer and show task and navigation shortcuts in a `?` help view.
- Respect configured bindings, suppress conflicting hints, and ignore key repeats when toggling help.
- Let the configured cancel key close help or cancel search and rename before dismissing the overview.
- Track overview dismissal while disconnected and clear stale connection notices after reconnecting.
- Use picker defaults for task action and error dialogs, and the theme accent color for agent status titles.
## Testing
Add coverage for help rendering, cancel navigation, custom shortcut conflicts, and overview dismissal during reconnection. Update snapshots for the compact footer and narrow layouts.
