feat: make git commits optional with no_commit config setting

[peterlimg]

Fix #303

This fix is generated via vibe coding and not fully tested to cover all edge cases. Anyway, it works good for me. Before the PR is merged, you can try this feature by change the mcp config to:

{
  "mcpServers": {
    "codemcp": {
      "command": "/usr/local/bin/uvx",
      "args": [
        "--from",
        "git+https://github.com/peterlimg/codemcp@main",
        "codemcp"
      ]
    }
  },
  "globalShortcut": "Shift+Space"
}

Hi! Can you send the prompts you used? (Full transcripts even better.) Thanks!

Hi @ezyang, it's some simple prompts I do on Windsurf with Claude 3.7.

Check the code and see if we can make it to support no git commit

That prompt basically did all the changes in commit 4a40a0f

Then I can see files will not be committed automatically, but one issue was that when files were untracked (not committed), updating them in new chat with codemcp will fail. From the error logs I can see he write_file, edit_file failed. So did another prompt to fix it:

write_file, edit_file requires git commit, fix it to do not rely on it

This prompt did changes on 66885cb
