fix(tui): allow session interrupt (ESC) when dialog is open

Issue for this PR

Closes #27922

Type of change

• Bug fix

What does this PR do?

When a permission dialog (or any dialog) is open in the TUI, the session_interrupt keybind (double ESC) is completely blocked because dialog.stack.length > 0 disables all keybindings. This creates an infinite dialog loop where the user can only dismiss one dialog at a time while the model keeps retrying.

Two changes in component/prompt/index.tsx:

1. Split session.interrupt into its own useBindings call without the enabled: command.matcher guard, so it's always reachable regardless of dialog state.

2. Remove the if (!input.focused) return check from the interrupt handler, so it works even when the prompt input is blurred by an open dialog.

These are minimal changes — all other keybinds remain correctly blocked when dialogs are open. Only session.interrupt is exempted.

How did you verify your code works?

This fix has been running in our fork (based on v1.14.41) for several days. Verified that:

• Double-ESC cancels the session even when a permission dialog is showing
• Single ESC still dismisses individual dialogs as before
• Other keybinds remain blocked during dialog display
• No regressions in normal dialog flow

  • feat(opencode): Add "Cancel" action on Message Actions Dialog to cancel a queued user prompt #27399
  • Why related: This PR also addresses cancellation in dialogs but takes a different approach (adding a "Cancel" action button). PR fix(tui): allow session interrupt (ESC) when dialog is open #27917 addresses the underlying keybind issue that makes session interruption impossible when dialogs are open. These PRs complement each other but tackle the problem from different angles.

No complete duplicates found. PR #27917 appears to be addressing a unique root cause that other PRs haven't tackled.
