Clarify advantages of git-mcp vs GitHub's official MCP

GitHub MCP already provides:

Repository file access Code search Commit history and diffs Branch/tag navigation Plus GitHub-specific features (issues, PRs, releases, discussions)

Questions:

What specific advantages does git-mcp offer over GitHub MCP? Are there use cases where git-mcp is clearly the better choice?

Suggestion: Adding a comparison section in the README would help users choose the right tool based on their requirements.
