step_executor gains three dispatch modes: pulse (default), hold
(hold_until_confirm), and value (transfer_move_to writes the target
station's code). The engine now sends step.stop_command_role whenever
cancel_on_fault is true on Faulted entry, and threads a target-station
lookup ahead of dispatch. A new simulate module patches the resolved
confirm signal after a short delay when SIMULATE_PLC is set, so
segments can be driven end-to-end without a real PLC.

Land design doc §12 P1 + P2: ops business tables plus station/segment
configuration endpoints. The engine (P3) consumes these as its inputs.
- Migration: six ops tables (station, station_signal, process_segment,
segment_step, segment_interlock, segment_resource) plus event attribution
columns (subject_type, subject_id).
- model.rs: FromRow structs and string-backed enum helpers
(StationType, StationSignalRole, SegmentMode, ActionKind, OnTimeout,
InterlockAppliesTo, RuleKind).
- service: station CRUD with signal-binding upsert; segment CRUD with
nested step/interlock CRUD and transactional resource replacement.
- handler: 13 endpoints covering design doc §9.1 config routes with
validator-based input checks and enum allowlists.
- router: wires the new routes; smoke tests cover station and segment
collection routes.

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.

- Move source/point/equipment/tag/page handlers from feeder to plc_platform_core
using State<PlatformContext>; feeder re-exports via handler modules
- Keep batch_set_point_value in feeder (requires app-specific write key auth)
- Add PlatformEvent enum and persist_and_broadcast() in core for platform event
persistence to DB + WebSocket broadcast
- Add PlatformContext::emit_event() that handles both sink notification and
async persistence in one call
- Add platform_routes<S>() in core for centralized route registration;
both feeder and ops merge it instead of duplicating route definitions
- Implement FromRef<AppState> for PlatformContext in both apps
- Add FeederPlatformEventSink adapter bridging core events to feeder's
EventManager + ControlRuntimeStore
- Add event namespace prefixes: platform.source.created, feeder.unit.fault_locked, etc.
- Register full platform CRUD routes in ops app

- PlatformContext now holds pool, connection_manager, ws_manager
- bootstrap_platform returns PlatformBuilder for pre-Arc setup
- Feeder AppState embeds PlatformContext (state.platform.pool etc.)
- Ops AppState embeds PlatformContext with real DB connection
- Remove WebSocket type duplication: feeder re-exports from core
- Add subscribe_room/send_to_room/remove_room_if_empty to WebSocketManager
