Bump the aru package version. Accepts an optional argument: major, minor, or patch. Default is minor if no argument is provided.

Steps

1. Parse argument: Read the argument (if any). Accept major, minor, or patch (case-insensitive). If no argument is given, default to minor. If the argument is not one of these three, report an error and stop.

2. Read current version from both files:

   • pyproject.toml — look for version = "X.Y.Z" under [project]
   • aru/__init__.py — look for __version__ = "X.Y.Z"
   • Both must match. If they differ, report the conflict and stop.

3. Calculate new version based on the bump type:

   • major: increment MAJOR by 1, reset MINOR and PATCH to 0. Example: 0.5.1 → 1.0.0
   • minor: increment MINOR by 1, reset PATCH to 0. Example: 0.5.1 → 0.6.0
   • patch: increment PATCH by 1. Example: 0.5.1 → 0.5.2

4. Update pyproject.toml: Replace the version value under [project] with the new version.

5. Update aru/__init__.py: Replace the __version__ assignment with the new version.

6. Confirm: Report the bump type, old version, and new version to the user (e.g. minor: v0.5.0 → v0.6.0).

Rules

• Both files must always have the same version number
• Use semantic versioning format: MAJOR.MINOR.PATCH
• Do not modify any other lines in either file
• Never ask the user for the version — derive it automatically from the files
