HistoryRead is served server-side by IHistorianDataSource; nothing ever dispatched
to a driver's IHistoryProvider. Removes IHistoryProvider, the OpcUaClient history
passthrough, DriverCapability.HistoryRead (+ resilience tier rows and AdminUI row),
HistoryReadStatusException and its node-manager catches, and the tests that only
covered them. Shared result types and HistoryAggregateNotSupportedException stay
(moved to Historian/HistoryReadContracts.cs). A stored ResilienceConfig still
carrying a HistoryRead key parses (diagnostic only; new test).

NamespaceMap now carries a RawPath -> upstream node id table built from the
deployed RawTagEntry list (reads each tag's TagConfig.nodeId, threads
WriteIdempotent). Under v3 the read/write/subscribe/history reference handed to
the driver is the tag's RawPath identity; the driver resolves it in two stages:
RawPath -> nodeId string (instance TryResolve) -> live NodeId re-bound against
the session (static TryResolve). Alarm ConditionId + event-history sourceName
stay on the direct session parse (they are upstream node ids, not RawPaths).
- Options: add IReadOnlyList<RawTagEntry> RawTags (Contracts now refs Core.Abstractions).
- Factory: RawTags binds straight into options (no separate DTO); EndpointUrl kept.
- Browser: unchanged (emits neutral BrowseNode DTOs, no TagConfig FullName key).
- Tests: 138 green; new RawPath resolution + factory-binding coverage; migrated
the stale-session ReadRaw test to author a resolving RawTag.
Contracts + Driver + Browser build clean (0 warn). Wave C wires endpoint->DeviceConfig
and the deploy artifact that populates RawTags.
Closes the code-review coverage gap: AcknowledgeAsync now has its own
swap-across-the-gate regression test (CallAsync lands on the post-gate
session), the subscribe-path coverage gap is documented, and the bounded
fallback drops from 2s to 250ms (the buggy-path signal is a synchronous
pre-await read, so it always wins well inside the bound).
