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 fewer duplicate label warnings.
what:
- Bump gp-sphinx and sibling package pins from 0.0.1a6 to 0.0.1a7
- Regenerate uv.lock
