Cleaned-up local files incorrectly marked as "committed"

[Vachhani-Tapan]

🐛 Bug Description

sync_pending_state() marks files as status "committed" when they are no longer dirty in VS Code. These files have NOT been committed to GitHub — they were merely cleaned up locally or reverted.

🔁 Steps to Reproduce

1. Make changes to a file so it appears as staged.
2. Discard the changes locally (revert to original).
3. Check the file status in the database via the Telegram bot /log command.

✅ Expected Behavior

Files that were reverted or cleaned up locally should be marked as "cancelled" or "removed", not "committed".

❌ Actual Behavior

The status bar and Telegram bot show these files as "committed", polluting the commit history with phantom commits.

🌍 Environment

Field	Value
OS	Any
VS Code version	Any
GitPhone extension version	Any
Python version	Any

📋 Additional Context

File: backend/supabase_service.py:242-277
Fix: Change the status to "cancelled" or "removed" instead of "committed" when files are no longer dirty.
