Codec<T> class abstract interface

A reversible encoder for a value of type T to / from a JSON-compatible representation.

Object? covers any value accepted by dart:convert.JsonCodec: null, bool, int, double, String, List<Object?>, or Map<String, Object?>. The actual concrete type returned by encode depends on the implementation; CRDT codecs always return a Map<String, Object?> while primitive codecs return primitives.

Codecs are pure values: no state, no side effects, safe to share across isolates.
