TUI quit (q) feels destructive — reassure users tasks keep running

[chanakyav]

In the interactive dashboard (--watch), pressing q to quit feels scary — users worry it stops the running task, not just the viewer.

Feedback

"Also q for quit is scary if I just want to close out the live view. Worried that stops the whole thing"

Current Behavior

• q closes the dashboard — tasks continue running in tmux (safe)
• x stops the selected task (destructive)
• But there's no visual indication that q is safe and tasks keep running

The user has no way to know that q only closes the viewer without reading the docs.

Proposed Fixes

1. Show exit confirmation message

When q is pressed, briefly show a reassurance before exiting:

Tasks still running in background. Use `autopilot status` to check progress.

This prints to the terminal after the TUI exits (alternate screen buffer is cleared).

2. Add persistent status bar in TUI

Add a dim status line at the bottom of the dashboard:

 j/k navigate  Enter attach  x stop  l logs  d detail  r refresh  q close (tasks keep running)

Change "quit" → "close (tasks keep running)" in the footer. Makes it clear q is non-destructive.

3. Rename q action label

Minimal change — rename from "quit" to "close" in the footer:

Before:  j/k navigate  Enter attach  x stop  l logs  d detail  r refresh  q quit
After:   j/k navigate  Enter attach  x stop  l logs  d detail  r refresh  q close

Recommendation

Do both #1 and #3:

• Rename footer label from "quit" to "close" (1-word change in _build_footer_main)
• Print reassurance message after TUI exits (2 lines in status_interactive)

Tiny change, big confidence boost for new users.
