ruff format --check doesn't cover the core package or tests, only scripts/examples

[codeforester]

Summary

Lint coverage and format-check coverage diverge in CI: ruff check covers the core package and tests, but ruff format --check doesn't.

Details

.github/workflows/tests.yml:59 — ruff format --check scripts examples — vs :60 — ruff check lib/python/base_cli scripts examples tests.

Impact

Formatting drift in the 9k-line core library or the 11k-line test suite would never be caught in CI.

Suggested fix

Extend the ruff format --check invocation to also include lib/python/base_cli and tests.
