* feat: add pygit2 compatibility wrapper for standalone Desktop 2.0 installs
Add git_compat.py abstraction layer that wraps both GitPython and pygit2
behind a unified GitRepo interface. When CM_USE_PYGIT2=1 is set (by the
Desktop 2.0 Launcher for standalone installs), or when system git is not
available, the pygit2 backend is used automatically.
Key changes:
- New comfyui_manager/common/git_compat.py with abstract GitRepo base class,
_GitPythonRepo (1:1 pass-throughs) and _Pygit2Repo implementations
- All 6 non-legacy files updated to use the wrapper:
- comfyui_manager/glob/manager_core.py (14 git.Repo usages)
- comfyui_manager/common/git_helper.py (7 git.Repo usages)
- comfyui_manager/common/context.py (1 usage)
- comfyui_manager/glob/utils/environment_utils.py (2 usages)
- cm_cli/__main__.py (1 usage)
- comfyui_manager/common/timestamp_utils.py (repo.heads usage)
- get_script_env() propagates CM_USE_PYGIT2 to subprocesses
- git_helper.py uses sys.path.insert to find git_compat as standalone script
- All repo handles wrapped in context managers to prevent resource leaks
- get_head_by_name returns _HeadProxy for interface consistency
- Submodule fallback logs clear message when system git is absent
- 47 tests comparing both backends via subprocess isolation

* fix(pygit2): address review findings + bump version to 4.2b1
- C1: add submodule_update() after pygit2 clone for recursive parity
- C2: check subprocess returncode in submodule_update fallback
- C3: move GIT_OPT_SET_OWNER_VALIDATION to module-level (once at import)
- H1: use context manager in git_pull() to prevent resource leaks
- Bump version to 4.2b1, version_code to [4, 2]
- Add pygit2 to dev dependencies and requirements.txt
* style: fix ruff F841 unused variable and F541 unnecessary f-string
