Splits the 694-line topology.py into five submixin files plus a
composing TopologyMixin in topology/__init__.py:
_core.py (~225) topologies CRUD + _assert_pending /
_check_and_bump_version concurrency guards
lans.py (~115) LAN CRUD
deckies.py (~130) topology decky CRUD + list_running_topology_deckies
edges.py (~80) edge CRUD + status-event log
mutations.py (~165) live reconciler queue (atomic claim + state writes)
Sibling submixins call self._assert_pending and
self._check_and_bump_version; MRO resolves them onto TopologyCoreMixin
through the composed SQLModelRepository class.
