fix(identity): rsync ownership parity for numeric-ids, dirs, maps, fake-super (#286, #294)

- #286: --numeric-ids is a mapping modifier only; it no longer activates
  chown by itself (identity_active_enabled/owner/group predicates), and
  --fake-super stores the resolved mapping instead of real-chowning.
- #286: apply owner/group to directories via the deferred directory
  metadata path; capture+transmit+apply directory xattrs/ACLs (-aX/-aA),
  including default ACLs, in STATUS_MKDIR/STATUS_DIR_TIMES.
- #294: --usermap/--groupmap support inclusive ranges, '*', empty FROM
  (unnamed ids), and receiver-side TO name resolution; --chown mixing with
  a same-side map is rejected like rsync.
- Protocol 2.22.0 -> 2.23.0 (map wire entry gains from_hi + to_name;
  dir frames gain a bounded xattr block).
