py(deps): gp-sphinx 0.0.1a6 -> 0.0.1a7

why: Pick up the sphinx-argparse-neo multi-page duplicate-label
scoping fix landed in gp-sphinx PR #16 so docs builds on this branch
emit drastically fewer duplicate label warnings (64 -> 9 verified
against an editable install of the same fix).
what:
- Bump gp-sphinx, sphinx-argparse-neo, sphinx-autodoc-api-style pins
  from 0.0.1a6 to 0.0.1a7 in dev and docs groups
- Regenerate uv.lock
