OptimizationRunConfigurationJson

JSON codec for OptimizationRunConfiguration.

Mirrors the configuration of ksl.app.config.RunConfigurationJson:

• prettyPrint = true — human-readable output;

• encodeDefaults = true — optional fields always appear in the output so JSON files are self-documenting and round-trip stable across future default changes;

• allowSpecialFloatingPointValues = true — required because nested types (e.g. control bounds, replication length) may carry ±Infinity.

Sealed-class variants of SolverSpec, TemperatureSpec, CoolingScheduleSpec, and CESamplerSpec use kotlinx-serialization's default polymorphic encoding with a "type" discriminator carrying the @SerialName value of each subtype.
