chore(release): keep uv.lock in sync with release versions

release-please bumps pyproject.toml and adk/pyproject.toml but never
touched uv.lock, so the lock fell behind on every release. CI ran
uv sync without --locked, so the drift was not caught.

- Add toml extra-files entries so release-please sets the version of
  the agentex-client and agentex-sdk entries in uv.lock.
- Refresh uv.lock to 0.28.5.
- Run uv sync --locked in the CI lint and build jobs.

The jsonpath filter matches both @.name and @.name.value because
release-please 16.18.0 runs jsonpath over a tagged TOML tree where each
value is wrapped as {start, end, value}.
