fix: address PR review comments for 0416-simplify_dev_setup

* fix(ci): add PR comment with test summary and block on failure

Add a `comment` job to the test workflow that parses JUnit XML artifacts
and posts a sticky PR comment showing pass/fail counts per suite, with
failed test names listed in a collapsible section and a link to the run.

Guards against fork PRs (read-only token) and stale overlapping runs
(skips comment if PR head has moved past our SHA).

* fix(ci): use payload SHA for staleness check, handle missing artifacts

- Replace context.sha (merge commit SHA) with
  context.payload.pull_request.head.sha so the staleness guard
  compares the correct values and the comment actually gets posted
- Add continue-on-error to download-artifact so cancelled runs
  gracefully fall through to the "no test results" message

* fix(ci): show warning icon for zero-test suites instead of failure
