Fix eval workflows (#1228)

* Fix eval workflows

* Address review: secure two-phase PR comment & byte-based truncation

- skill-check.yml: Revert to pull_request trigger (read-only token).
  Remove PR comment posting; upload results as artifact instead.
- skill-check-comment.yml: New workflow_run-triggered workflow that
  downloads the artifact and posts/updates the PR comment with
  write permissions, without ever checking out PR code.
- skill-quality-report.yml: Replace character-based truncation with
  byte-based (Buffer.byteLength) limit. Shrink <details> sections
  structurally before falling back to hard byte-trim, keeping
  markdown rendering intact.
