What / 改了什么

Extend the existing test workflow to run on branch pushes as well as PRs and manual dispatch. Keep the 12 Linux/Windows/macOS × Python 3.10–3.13 combinations, and rerun the Windows Python 3.13 suite with desktop dependencies installed.

Add a 15-minute job timeout, cancel superseded runs, use the selected Python for dashboard tests, enable UTF-8, update the setup actions to v6, and pin the tested Node.js major to 22. Keep read-only repository permissions and disable checkout credential persistence. Update both READMEs.

Why / 为什么

Branch changes currently receive no push checks, and the optional Windows tray tests are skipped without their dependencies. This adds that coverage while keeping the standard-library-only run. Native tray and WebView2 smoke tests remain opt-in locally.

How was it tested? / 如何测试

Local macOS, Python 3.11.9, Node.js 22.23.2:

• python -m unittest discover -s skills/headroom/tests -p "test_*.py" -v with HEADROOM_DISABLE_DASHBOARD=1, HEADROOM_TEST_PYTHON=python3, and PYTHONUTF8=1: 70 passed, 10 skipped.
• node skills/headroom/tests/test_dashboard_mood.js: passed.
• actionlint 1.7.12 and git diff --check: passed.

The hosted matrix and Windows desktop dependency run have not yet been verified.

Checklist / 检查项

• Core code stays standard-library only; no product code or PowerShell changes.
• No prompt text, history, ledgers, or credentials committed.
• README.md and README.zh-CN.md updated together.
