[BUG] "View PR" button routes to merged PR instead of current PR when reusing branch name in same session

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

When working in the same Claude Code session:
Create PR #1 on branch claude/work-in-progress-<session-id>
Merge PR #1
Delete the branch
Continue in same session - branch gets recreated with same name
Create PR #2 on the same branch name
Click "View PR" button
Expected: Routes to PR #2 (active) Actual: Routes to PR #1 (merged)
Environment: Claude Code Web

What Should Happen?

I expect that you guys automate bug submission.
