CP-3473: adopt standardized ruff rule set + pyrefly ~=1.1 in squawk-pre-commit

[stephen-kintsugi]

Summary

• Adopt the standardized CP ruff lint rule set: extend-select = ["I", "F", "UP", "B", "SIM", "C4"] (was ["I", "F"]), matching kintsugi-platform, kintsugi-rules, and kintsugi-product-classification.
• Pin the ruff dev-dep to ~=0.13.3 (was ~=0.15.14, ahead of the fleet), matching the fleet anchor and the repo's own ruff-pre-commit hook already pinned at v0.13.0. The hook rev is unchanged.
• Bump pyrefly dev-dep ~=1.0.0 -> ~=1.1 and the pyrefly-pre-commit hook rev 0.53.0 -> 1.1.1.
• One code fix from the new rules: B904 on the _SquawkNotFound re-raise in squawk_alembic/hook.py, now raise _SquawkNotFound from None. No behavior change.

Lint/type tooling only. No functional changes, no other dep bumps.

Tests

• ruff check and ruff format clean on ruff 0.13.3.
• pyrefly check clean on 1.1.1 (0 errors).
• Full suite green: 49 passed.
• Full pre-commit run --all-files gate passes; ruff-format confirmed stable on a second run (no modifications).

Note

Low Risk
Dev-only lint/type pins and a non-behavioral exception chaining tweak; no runtime or security-sensitive logic changes.

Overview
Aligns squawk-alembic dev tooling with the CP fleet: ruff’s extend-select now includes UP, B, SIM, and C4 (not just import/sort and pyflakes), the ruff dev dependency is pinned to ~=0.13.3 (down from 0.15.x to match other repos and the existing ruff-pre-commit hook), and pyrefly moves to ~=1.1.1 with the pyrefly-pre-commit hook rev updated to 1.1.1. poetry.lock and package version 0.3.4 reflect those bumps.

The only application code change is a B904 fix in squawk_alembic/hook.py: missing squawk binary now raises _SquawkNotFound with from None so the FileNotFoundError chain is suppressed; user-facing behavior is unchanged.
