RunConfigurationJson

JSON codec for RunConfiguration.

Wraps the standard kotlinx-serialization-json serializer with settings appropriate for run configuration documents:

• prettyPrint = true — human-readable, reviewable output

• encodeDefaults = true — optional fields (e.g. TracingConfig) always appear in the output, making JSON files self-documenting and round-trip stable regardless of which defaults change in future versions

• allowSpecialFloatingPointValues = true — required because ksl.controls.ControlData bounds and ksl.controls.experiments.ExperimentRunParameters.lengthOfReplication can be ±Infinity

These settings mirror those used by ksl.simulation.ModelDescriptor.toJson.
