ci: add GitHub Actions workflow to run tests on PRs

Previously no CI workflow ran pytest on pull requests, so
regressions could land undetected. This adds a test.yml
workflow triggered on PRs and pushes to main.

- Split into three parallel jobs: core, inspect, helm
- Core job runs tests that need no optional dependencies
- Inspect and HELM jobs install their respective extras
- Pin action versions to match regenerate_types.yml
- Add timeout-minutes: 10 to guard against hung jobs
- Update uv.lock

Closes #88
