A registry directory that is itself a symlink got two audit logs: submit
resolved --registry-dir with pwd -P and wrote next to the target, while logs
derived the sibling from the link path. sibling_logs_dir() now takes the
registry's realpath; an explicit DELEGATE_JOB_LOGS_DIR still wins.
Also: forwarded_keys() normalises both sides of its comparison, and the
design doc's status row lists the audit log next to the registry.

control_plane and status.sh imported sibling_logs_dir from mqtt_common,
which imports paho at module level, so create/resume's binding and status
died on an interpreter without paho-mqtt (_delegate_py_bin's last fallback
is the PATH's python3). The registry/audit-log path rules move to
lib_py/delegation/logroot.py (standard library only) and mqtt_common
re-exports them. The package's own import chain also reached paho through
service -> publish_event -> publisher, so mqtt_common and publisher import
paho tolerantly and make_client() refuses with a clear error when a broker
is actually needed. control_plane, status.sh, lib.sh's delegate_publish_cmd
and delegate_logs_dir, and the wrapper's _logs_dir_abs import from logroot.
