Krzysztof kuhy Rudnicki 6154dc09bf Pin pre-commit's ruff to 0.16.7 and satisfy the CPY001 it brings
The three Python packages pinned ruff twice at different versions:
requirements.txt at 0.16.7, .pre-commit-config.yaml at v0.15.2. Only the
older one ever ran, so `select = ["ALL"]` was enforced two minor versions
behind. Measured before aligning: v0.15.2 reports 0 findings, every 0.16.x
reports CPY001 on each file -- 70 crdt-sync, 23 freedays, 71 gatelock, and
no other rule.

Resolved by adding the notice rather than ignoring the rule, so the gate
keeps its teeth.

Two gatelock modules sat at exactly the 250-line cap, so a one-line header
tipped them to 251. Both are split along a real seam rather than shaved:

  _widget_fills.py    colour arithmetic over LockConfig, no tkinter import
  _surfaces_focus.py  selects among existing surfaces, never mutates them

The focus split keeps _surfaces.py's documented containment (it stays the
only module that creates, moves or destroys windows), and the static guard
in test_recovery_invariants.py globs _surfaces*.py, so the new sibling is
covered with no list to extend. widgets.py re-exports the fills helpers,
which keeps gatelock.widgets the single public surface its tests import.
