chore(release): v0.13.0 (#148)

Promote 0.13.0rc1 to the 0.13.0 real release after the rc verified
clean on TestPyPI (fresh-venv install, version + [otel] import, and
hello-world run against a real endpoint). Flip pyproject version,
__version__, and the test_smoke assertion to 0.13.0; regenerate
AGENTS.md for the version string; refresh uv.lock. CHANGELOG needs no
change: the [0.13.0] heading and 2026-06-09 date already match the
tag day.

After this PR merges, push the v0.13.0 tag from a freshly pulled main
to publish to PyPI and create the GitHub Release.
