- IDriverProbe abstraction in Core.Abstractions; one impl per driver
type, resolved by DriverType string. Phase 7.3 + 7.4 add concrete
probes for the 9 supported driver types.
- TestDriverConnect / TestDriverConnectResult messages.
- AdminOperationsActor.HandleTestDriverConnectAsync looks up the probe
by DriverType, runs it with a [1,60]s clamped timeout, and returns
success/latency or failure/message. Probes that throw or time out
surface as soft failures.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
