py(deps[dev]) ruff 0.16.2 -> 0.16.3

why: Reviewed against this repository and inert. 0.16.3 changes S602,
S603, S607 and S609 to also inspect keyword arguments; the only
flake8-bandit rules selected here are S102, none of which
changed. UP048 and the PLR6104 false-negative fix are preview-only and
preview mode is off in this project. What does land is a faster binary:
0.16.3 builds Linux x86-64 with PGO and shrinks `Expr` to 64 bytes.

what:
- uv.lock: ruff 0.16.2 -> 0.16.3 (floor `ruff>=0.16.1` unchanged)
