[UX] Ctrl+D to delete session too easily exits the app #13950

Description

Pressing Ctrl+D twice to delete a session is problematic because the same keybind also exits the application. In practice, if you press Ctrl+D once and then press it again slightly later — or accidentally press it when not in the session list — it exits the entire app.

This happens constantly during normal usage. You intend to delete a session, but the double-press of Ctrl+D is interpreted as "exit the app" instead. Losing the app state to an accidental exit is really frustrating.

Steps to Reproduce

1. Open OpenCode TUI
2. Press Ctrl+D intending to delete the current session
3. Press Ctrl+D again (either for confirmation or by accident)
4. Expected: Session is deleted
5. Actual: The app exits

Suggested Fix

• Use a different keybind for app exit (e.g. Ctrl+Q), so Ctrl+D is exclusively for session deletion
• Or require a confirmation prompt ("Are you sure you want to exit?") before quitting
• Or significantly increase the timeout window between the two presses so they aren't confused
