Unused variable fetch in force commit handler

[Vachhani-Tapan]

🐛 Bug Description

Line 1153 of bot.py fetches file_ids_for_force from user_data but does NOT assign it to any variable — the result is immediately discarded.

🔁 Steps to Reproduce

1. Trigger a force commit flow.
2. Observe that file_ids_for_force is fetched but never used to filter staged_rows.

✅ Expected Behavior

The file_ids_for_force should be used to filter which files are included in the force commit.

❌ Actual Behavior

The force commit logic may include files that were not part of the original conflict set, since file_ids_for_force is never used.

🌍 Environment

Field	Value
OS	Any
VS Code version	Any
GitPhone extension version	Any
Python version	3.11+

📋 Additional Context

File: backend/bot.py:1152-1153
Fix: Assign and use the fetched value to filter staged rows.
