docs(deps[gp-sphinx]) bump 0.0.1a13 → 0.0.1a16 (#526)

Pulls in the sphinx-vite-builder consolidation from
git-pull/gp-sphinx#29. Docs site now renders via `gp-furo-theme`,
a Tailwind v4 respin of Furo; `sphinx-vite-builder` owns the Vite
asset pipeline so wheels ship with the static tree pre-baked.

- **Bump**: gp-sphinx workspace pins to `0.0.1a16` across
  pyproject.toml + uv.lock
- **Cleanup**: legacy `gp-sphinx-vite` references dropped
  (package retired in favor of `sphinx-vite-builder`)
- **CHANGES**: bullet under unreleased Documentation noting the
  rendering switch

See: https://pypi.org/project/gp-sphinx/0.0.1a16
