- Bump all active workflows to action versions that natively target Node 24:
checkout@v6, setup-node@v6, cache@v5, upload-artifact@v7, download-artifact@v8.
Resolves the "Node.js 20 is deprecated" warning in CI logs. The kept
`FORCE_JAVASCRIPT_ACTIONS_TO_NODE24` env stays as a no-op safety net (also
in upstream OpenCode).
- test-runner: when running under GitHub Actions, emit a `::warning::`
annotation per flaky file and append a markdown table to
`$GITHUB_STEP_SUMMARY`. mikepenz/action-junit-report already surfaces
failures from the JUnit XML, but flakies pass cleanly on retry and were
invisible in the UI.
