• feat: add PROTO.Cached<V> serializer 615cf12

  function Cached<V>(s: PROTO.Serializable<V>, depth?: number): PROTO.Serializable<V>

  Adds an LRU‑based caching wrapper for existing serializers.
  The cache stores serialized output for up to N distinct values and evicts the least‑recently‑used entry when the limit is exceeded.
  This reduces redundant serialization work and improves performance on repeated inputs.

  const cached = PROTO.Cached(PROTO.String, 32);

  In a benchmark repeatedly serializing "Hello World!", the cached serializer was 2x faster than the uncached serializer.
  This performance benefit increases with larger data sizes.
