Scala Kindlings Derivation

Quick start

• Use Kindlings to derive type class instances; keep using library APIs for actual work.
  • Circe: derive Encoder, Decoder, or Codec.AsObject; keep using asJson, decode, parsers, printers.
  • PureConfig: derive ConfigReader, ConfigWriter, or ConfigConvert; keep using ConfigSource.load and PureConfig writers.
• Prefer companion-object instances for root types used at call sites; nested product types are derived as needed.
• Configure derivation with Kindlings config values/hints, not with Circe/PureConfig generic imports.
• Do not import io.circe.generic.auto._, io.circe.generic.semiauto._, pureconfig.generic.auto._, or pureconfig.generic.semiauto._ when using Kindlings.
