- H3: a daemon module without 'client owner = yes' now also has super-user
device activity forced off (char/block mknod, --write-devices), so a root
daemon can no longer be made to create/write raw devices under AUTO. The
entries are skipped, preserving ordinary -a pushes.
- H1/H2: propagate a failed required --copy-as chown from symlink metadata
restore and implicitly-created parent directories, so the entry (and run)
reports failure instead of a wrong-owner success.
- Docs/help/headers updated for A2/A3 and the device clamp; startup warning
spells out the client-owner risk.
- Tests: daemon device clamp (skipped without opt-in, created with opt-in),
updated --super/--fake-super expectations.
