fix(ci): handle "No issues found" comment + restore version-check [skip-regression-check]

1. Handle Claude's "No issues found" comment as a clean pass instead
   of treating empty BODY as blocking. Checks for this before looking
   for "Found N issues" comments.

2. Restore version-check to run on all PRs (not just staging-promotion).
   It's 4-8 seconds and catches missing version bumps early.
