Joseph Doherty 98bf2d0da4 Expand SnowBridge to own ingest + in-process transform; drop dbt ...

SnowBridge now owns machine-data ingest, in-process .NET transformation,
and direct writes to curated tables in Snowflake. Collapses the previous
ingest/transform split into a single service; no dbt, no external
orchestrator, no Snowflake landing tier. Keeps the in-house .NET pattern
consistent with ScadaBridge and OtOpcUa.

The "Snowflake dbt Transform Layer" roadmap workstream merges into
SnowBridge (7 → 6 workstreams); Year 2 canonical-state-based OEE moves
with it. Canonical model still has three surfaces — the third is
renamed from "dbt curated layer" to "SnowBridge curated layer in
Snowflake"; mechanics unchanged.

Add _base equipment-class template for universal cross-machine metadata that every machine in the OtOpcUa estate exposes regardless of vendor, protocol, or machine type. References OPC UA Companion Spec OPC 40010 (Machinery) for the Identification component (Manufacturer, Model, ProductInstanceUri, SerialNumber, HardwareRevision, SoftwareRevision, YearOfConstruction, ManufacturerUri, DeviceManual, AssetLocation) plus the MachineryOperationMode enum (Auto, Manual, Maintenance, Service, Setup, Other), OPC UA Part 9 for the alarm summary fields (HasActiveAlarms, ActiveAlarmCount, HighestActiveAlarmSeverity), ISO 22400 for the lifetime counter fields (TotalRunSeconds, TotalCycles) that feed Availability + Performance KPIs at Layer 3, and the 3-year-plan handoff §"Canonical Model Integration" for the canonical state vocabulary (Running / Idle / Faulted / Starved / Blocked) declared in _base.stateModel. Includes the OtOpcUa five-identifier set (EquipmentUuid, MachineCode, ZTag, SAPID, plus DeviceClass = EquipmentClassRef) so every machine surfaces the join keys downstream consumers need; ConnectionState + LastDataTimestamp + DriverType for driver-side observability that does not require any particular equipment-protocol feature; optional production context (CurrentWorkOrder, CurrentPartNumber, CurrentRecipe, CurrentOperator, CurrentShift) marked isRequired: false since not every machine type surfaces these. Plus two universal alarm definitions (communication-loss, data-stale) that apply to every equipment regardless of class.
