fix: stabilize npm version and rebuild-from-specs hook for CI

- Convert setuptools-scm version to base semver (X.Y.Z) for npm
  compatibility. Dev/local suffixes change with every commit, causing
  the rebuild-from-specs hook to perpetually modify js/package.json.
- Remove pyproject.toml from rebuild-from-specs trigger pattern since
  the version is now determined by git tags, not pyproject.toml.
