This update introduces Variant B behavior in the command resolver:
- If a repository explicitly defines the key \"command\" (even if its value is None),
resolve_command_for_repo() treats it as authoritative and returns immediately.
This allows library-only repositories to declare:
command: null
which disables CLI resolution entirely.
- As a result, Python package repositories without installed CLI entry points
no longer trigger SystemExit during update/install flows, as long as they set
command: null in their repo configuration.
The resolution logic is now bypassed for such repositories, skipping:
- Python package detection (src/*/__main__.py)
- PATH/Nix/venv binary lookup
- main.sh/main.py fallback evaluation
A new unit test suite has been added under
tests/unit/pkgmgr/core/command/test_resolve.py
covering:
1) Python package without installed command → SystemExit
2) Python package with installed command → returned correctly
3) Script repository fallback to main.py
4) Explicit command overrides all logic
This commit stabilizes update/install flows and ensures library-only
repositories behave as intended when no CLI command is provided.
