## What changed
Add macOS-only integration coverage that runs commands under the production
Seatbelt policy and verifies:
- deny globs protect matching files, directory ancestors, symlink aliases, and
paths created after policy application;
- protected directories cannot be moved, replaced, or exchanged across
writable roots; and
- standard read-only and workspace-write profiles continue to allow expected
filesystem operations.
