"""Single source of truth for the YouOS version.

Several places had hardcoded version strings that drifted (settings default,
/api/config, the UI footers). This resolves the version once. YouOS is a
repo-based local-first app, so ``pyproject.toml`` is the truth and stays
correct without a reinstall; installed package metadata is the fallback for a
non-editable install.
