py(deps) Bump gp-sphinx workspace pins to 0.0.1a10

why: gp-sphinx cut 0.0.1a10 covering the merged seo-packages PR
(sphinx-gp-opengraph + sphinx-gp-sitemap, register-aware
autodoc-docutils discovery, post-audit bug fixes). libtmux-mcp
should track the latest workspace alpha so its docs build picks
up the SEO emission and the corrected sitemap behaviour.

what:
- pyproject.toml: gp-sphinx, sphinx-autodoc-api-style,
  sphinx-autodoc-fastmcp pins move 0.0.1a9 → 0.0.1a10 in both the
  main and dev dependency groups.
- uv.lock refresh is deferred until 0.0.1a10 publishes to PyPI.
  The lock currently resolves the 0.0.1a9 line, which is what
  ``uv sync --locked`` will install until the next ``uv lock``
  follow-up.
