File	Description
composer.json	Added exact version constraint for phpstan at 2.1.33 to prevent automatic updates that break rector compatibility
composer.lock	Updated lock file to reflect phpstan downgrade from 2.1.34 to 2.1.33
app/Services/GitHubService.php	Removed redundant variable assignment and null check since Cache::remember() closure always returns int

[Copilot]

The exact version pin for phpstan (without ^ or ~) will prevent automatic patch updates. While this is appropriate as a temporary workaround for the rector compatibility issue, consider documenting this constraint (e.g., adding a comment explaining why it's pinned) or tracking when it can be unpinned once rector is updated to support newer phpstan versions.
