• Replace AvroBinaryCodec with AvroCodec across the Avro module and update codec derivation in AvroFormat.
• Update Avro-related tests/utilities and documentation to reference AvroCodec.
• Update Avro benchmarks to use the renamed codec type.

• AvroBinaryCodec was renamed/replaced with the public AvroCodec type, but the new public abstract class currently has no Scaladoc. To keep docs consistent with other codecs (e.g., JsonCodec), please add Scaladoc describing what AvroCodec does, how decodeUnsafe/encode relate to BinaryDecoder/BinaryEncoder, and include an example of deriving a codec via AvroFormat plus accessing avroSchema.
