Interactive TUI dashboard with keybindings

[chanakyav]

Problem

autopilot status --watch currently provides an auto-refreshing table display but is non-interactive — you can only watch, not act.

Inspired by gavraz/recon's table view, we should add an interactive TUI with keybindings to the --watch mode:

Proposed Keybindings

Key	Action
j / k	Navigate sessions up/down
Enter	Attach to selected session (switch tmux)
x	Kill/stop selected session
i / Tab	Jump to next session waiting for input
r	Force refresh
q / Esc	Quit

Implementation Notes

• Could use rich + textual for the TUI, or a lighter-weight approach with raw terminal handling
• The current _status_watch function with rich.live.Live is the foundation
• Session state is already in SQLite so polling is cheap
• tmux integration (switch-client, kill-session) already exists in cmd_attach and cmd_stop

Context

This was intentionally deferred from PR #10 which shipped the simpler --watch auto-refresh as a first step.
