This commit introduces the `git branch` tool to the MCP Git server, allowing users to list branches with various filtering options.
Changes include:
- Implemented `git_branch` function in `src/git/src/mcp_server_git/server.py` to support listing local, remote, and all branches, as well as filtering by `contains` and `not_contains` SHA values.
- Added comprehensive unit tests for the `git branch` functionality in `src/git/tests/test_server.py`, covering different branch types and commit filtering scenarios.
- Updated `src/git/README.md`.

- Updated `src/git/README.md`.
- Introduced `GIT_DIFF_CONTEXT_LINES` environment variable to customize the number of context lines shown in git diff output.
- Updated `git_diff_unstaged`, `git_diff_staged`, and `git_diff` functions to utilize the new context line setting.
- Enhanced README.md to document the new environment variable and its implications.
The git server currently lacks branch switching capabilities, limiting both
LLMs and developers. This adds branch checkout so LLMs can
help developers add new functionality in a new feature branch.
