protect-files.sh blocks Edit/Write to secrets, lock files, default
Laravel migrations, the deleted apps/admin/ tree, .claude/ itself,
and dev-docs/SCHEMA.md.
block-dangerous-bash.sh blocks destructive git operations, blanket
dependency updates, and database wipes that aren't scoped to the
testing environment.
Both signal block via exit 2 with a reason on stderr; both stay well
under 500ms per invocation.
