The arch-review #10 sub-gap worried that per-instance ResilienceConfig never
reaches the runtime pipeline. The threading is in fact wired end-to-end (task #13):
ConfigComposer serialises the whole DriverInstance entity, so ResilienceConfig
rides the artifact into DriverInstanceSpec, which DriverHostActor layers onto the
driver's Polly pipeline. The only leg with no test was the real composer->artifact
serialization — the existing DeploymentArtifactTests hand-build the JSON.
Adds ResilienceConfig_survives_ConfigComposer_to_ParseDriverInstances_round_trip
(mirrors the DeviceHost round-trip guard): seeds a DriverInstance WITH a non-default
override + one WITHOUT, runs the real SnapshotAndFlattenAsync, and asserts
ParseDriverInstances recovers the override byte-for-byte (and null stays null).
Guards against a future projection / [JsonIgnore] silently reverting authored
resilience policy to tier defaults while hand-built artifact tests stay green.
ControlPlane.Tests ConfigComposerTests 6/6 green.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
