py(deps[uv]) Bump gp-sphinx workspace pins to 0.0.1a14

why: Pick up the gp-sphinx 0.0.1a14 release, which fixes a light-mode
distinguishability gap in the gp-sphinx-light Pygments style:
Generic.Prompt is now coloured purple and Generic.Output cyan, so
shell prompts ($, >>>, etc.) and command output stand out from
surrounding text. Previously both fell through to a generic slate
that matched section sub-headings, leaving prompts and command output
visually indistinguishable. Mirrors the dark-mode (monokai) pink +
cyan pairing already in place.

what:
- pyproject.toml: gp-sphinx, sphinx-autodoc-argparse, sphinx-autodoc-api-style move ==0.0.1a13 -> ==0.0.1a14 in
  [dependency-groups] dev and docs.
- uv.lock: regenerated; gp-sphinx workspace siblings (sphinx-gp-theme,
  sphinx-ux-autodoc-layout, sphinx-ux-badges, sphinx-fonts, etc.)
  co-resolved to 0.0.1a14.
