Refactor version management to use dedicated version module

[imtoopunkforyou]

Added

• New version.py module that extracts package metadata (version, author, author email, license) from importlib.metadata

Changed

• __init__.py now imports and uses VERSION from the new version module instead of calling importlib.metadata.version() directly

Removed

• Direct import of version from importlib.metadata in __init__.py
