release(deps[gp-sphinx]) bump 0.0.1a18.dev0 → 0.0.1a18

why: gp-sphinx 0.0.1a18 is now live on PyPI with the curated
autodoc rendering work from PR git-pull/gp-sphinx#36 (merged to
main). The dev0 scaffolding can come out.

what:
- bump every gp-sphinx workspace pin from 0.0.1a18.dev0 to 0.0.1a18
- remove [tool.uv].prerelease = "allow" — no longer needed now
  that the dev marker is gone
