[FEATURE] ability to clear stale unsent / unacknowledged prompts

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently when there’s a connection issue, I can get stale prompts cluttering up the UI.

Proposed Solution

Would be great to have a close / delete button on each to cancel these.

Alternative Solutions

Workaround is dealing with less space in the UI with more scrolling back and forth past the stale prompts, or starting a new session and losing context.

Priority

Medium - Would be very helpful

Feature Category

Interactive mode (TUI)

Use Case Example

1. working on any app
2. submit a prompt
3. if connection drops, there’s a chance the prompt goes stale, remains unsent even after connection restored
4. if this happens a few times then the UI is dominated by the stale prompts between the input box and most recent response
