`detect_conflict()` is dead code — never called

[Vachhani-Tapan]

🐛 Bug Description

The detect_conflict() function in diff_service.py is defined but never called anywhere in the codebase. The actual conflict detection logic is implemented inline in github_service.py.

🔁 Steps to Reproduce

1. Search for any import or call to detect_conflict from diff_service.py across the codebase.
2. Find zero references.

✅ Expected Behavior

Either the function should be removed or it should be used for conflict detection.

❌ Actual Behavior

Dead code exists in the codebase adding unnecessary maintenance burden.

🌍 Environment

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

📋 Additional Context

File: backend/diff_service.py:33-41
Fix: Remove the unused function or refactor github_service.py to use it.
