Fix: Detect PR creation from CLI in changes panel

[rabanspiegel]

Problem

When a PR is created through the "Create PR" button, the changes panel immediately detects it — the onSuccess callback triggers refreshPr(), CI checks appear, and the UI updates instantly.

When a PR is created via the CLI (e.g. gh pr create in the agent terminal or a shell tab), the changes panel doesn't notice until the next background poll cycle (up to 30s) or window re-focus. During that gap, the panel still shows "Create PR" and CI checks aren't visible.

Desired Behavior

PR detection should work identically regardless of how the PR was created — button or CLI.

Possible Approaches

1. Manual refresh — Add a refresh button to the changes panel header so the user can trigger a PR status check when they know one was created. Simple, no performance cost.

2. PTY output detection — Watch terminal output for GitHub PR URL patterns (https://github.com/.../pull/\d+). When detected, trigger an immediate refreshPrStatus(). Event-driven, no extra polling.

Either way, the goal is instant detection without increasing background poll frequency.

Hy @arnestrickmann @rabanspiegel
Thanks for the detailed feedback on the previous PR.

I've opened a new PR that incorporates the suggested changes:
#1305

Updates made:

• Resolved the merge conflicts in ptyIpc.ts and ptyManager.ts.
• Simplified the PR detection logic using the regex-based approach you suggested.
• Removed the tail buffer and cooldown map to reduce complexity.
• Applied the renderer fix in useAutoPrRefresh to avoid refreshing the wrong task when cwd is undefined.
• This keeps the feature lightweight (~30–40 lines) while still enabling instant PR detection when running gh pr create in the terminal.
• Please let me know if there’s anything else that should be adjusted. Happy to update further if needed. Thanks again for the guidance!
