py(deps[dev]) Require ruff>=0.16.1

why: A bug-fix release: no newly stabilized rules and no change to the
default rule set, so it surfaces no new diagnostics here. Verified by
running ruff against this repo at both versions; the finding set is
identical.

What it does change is three rules that were over-firing. B008 now
treats `range` as immutable, RET504 stops firing when the variable is
read in a `finally` clause, and D214, D405 and D413 skip section
detection inside RST directive bodies.

The floor earns its keep on fix safety rather than findings: 0.16.1
reclassifies PT022 and FURB105 fixes as unsafe, so a contributor still
resolving 0.16.0 would have `ruff check --fix` apply edits this
version now declines to make.

0.16.2 exists but is younger than the 3-day supply-chain cooldown and
is deliberately not taken.

what:
- ruff>=0.16.0 -> ruff>=0.16.1 in both pin sites (dev and lint groups)
- uv.lock: ruff 0.16.0 -> 0.16.1
