EventInsert + EventRecord + record_event now carry the subject_type /
subject_id columns added by the P1 migration. Ops events populate
"segment" / "station" subjects so the timeline can be filtered without
parsing event_type strings. Platform SourceCreated / Updated / Deleted
attribute themselves to subject_type="source". Adds get_events_*_filtered
in core and exposes GET /api/event on ops with event_type /
event_type_prefix / subject_type / subject_id query params, closing
design doc §14 "event 表能按 ops.* 和 subject_type/subject_id 查到全链路事件".

Wires AppState with EventManager, SegmentRuntimeStore, ResourceRegistry
and an engine supervisor that idles until P1 lands the segment schema.
The run() bootstrap connects enabled sources, installs a Ctrl+C handler,
and disconnects on shutdown, matching the feeder app lifecycle. The
router exposes /ws/public, /ws/client/{id}, simple_logger middleware
and a permissive CORS layer.
AppEvent covers the full ops.* taxonomy from the spec; resource lease
tracking includes heartbeat timestamps for the §7 recovery strategy and
has two unit tests for acquire/release semantics.
