E2E Tests for A1.9 Git Source Features

Tests the complete workflow with temporary files and repositories:
1. GitConfigRepo - clone/pull operations
2. SourceManager - registry CRUD operations
3. MCP Tools - all 4 git-related tools
4. Integration - complete user workflows
5. Error handling - authentication, not found, etc.

All tests use temporary directories and actual git repositories.
