Checklist for the fixing agent

• Commit fix to branch raptor/runtime-thunderbird-nightly (push to existing PR, or open a new one if none exists)
• If the fix reveals an app-specific quirk (e.g. local patch files, finish-args oddities, appstream gaps), document it in skills/app-gotchas.md under a ### thunderbird-nightly heading — commit to same branch
• If the fix reveals a gap in the sync script or pipeline (e.g. patch files not fetched on import), update the relevant skill in skills/ — commit to same branch
