Adds a test that scans all generated SKILL.md bash blocks for raw glob
patterns and verifies they have either a find-based replacement or a
setopt +o nomatch guard. The test immediately caught 2 unguarded blocks
in review.ts (design doc re-check and plan file discovery).
Also syncs package.json version to 0.12.8.1.
