chore: derive package version from git tags via hatch-vcs

Replaces the static project.version string with dynamic = ["version"],
sourced from the nearest git tag (hatch-vcs). Fixes docs.yml, which read
pyproject.toml's version field directly and would have broken once that
field stopped being a plain string; it now reads the resolved version via
importlib.metadata after `uv sync` installs the package.
