fix: recognize active generation after prompt send

[JJLiebig]

Summary

ChatGPT can clear the composer and start generating before Ask Pro's conversation-turn selectors see the submitted prompt. In that state Ask Pro incorrectly times out and labels a working Pro answer as a failed send. Accept a cleared composer with a visible Stop control as submission evidence, without treating a hidden Stop element as active.

Validation

• Focused prompt-composer tests, including the missed-turn and hidden-control cases.
• Plugin validation, build, lint, 307 tests, format check, and package dry run passed.
• Review Suite fast: both reviewers clean.

The ongoing Pro run was left untouched; this change has not been installed into its immutable runtime.

Summary by CodeRabbit

• Bug Fixes

  • Improved prompt submission detection when the composer clears before a new conversation turn appears.
  • Active, visible Stop controls now correctly confirm that a prompt was submitted.
  • Hidden Stop controls no longer incorrectly confirm prompt submission.

• Tests

  • Added coverage for visible and hidden Stop control scenarios.

• Documentation

  • Updated the changelog and Windows work notes with the revised behavior.

In `@src/browser/actions/promptComposer.ts`:
- Line 826: Update the isVisible helper used by verifyPromptCommitted to also
reject elements whose computed visibility is hidden or display is none, while
preserving the existing bounding-rectangle checks. Add coverage for a Stop
element with visibility hidden so the fallback cannot accept it as visible
without new-turn evidence.
