- Update pkgmgr.actions.branch.open_branch() to resolve the base branch
via _resolve_base_branch(), preferring 'main' and falling back to
'master' when the preferred branch does not exist.
- Adjust the open_branch logic to:
- fetch from origin
- checkout the resolved base branch
- pull the resolved base branch
- create the feature branch
- push the new branch with upstream tracking
- Add and refine unit tests in tests/unit/pkgmgr/actions/test_branch.py
to cover:
- normal branch creation with explicit name and default base
- interactive name prompting when no name is provided
- error handling when fetch fails after successful base resolution
- fallback to 'master' when 'main' is missing.
- Clean up and clarify docstrings and comments for open_branch(),
close_branch(), and _resolve_base_branch(), and fix the module header
comment to match the new package path.
This fixes branch opening in repositories that still use 'master' as
their primary branch while keeping the default behavior for 'main'.
