Subject: [PATCH] Use setuptools-scm for automatic version management

Replace manual version management with setuptools-scm which derives the
version from git tags at build time. This eliminates the need for a
workflow to push version updates back to main (which required a PAT).

- Add setuptools-scm as build dependency
- Make version field dynamic in pyproject.toml
- Update publish workflow to use setuptools-scm
- Remove update-version.yml workflow
