/**
 * Protocol Buffers wire types.
 *
 * `ProtobufWire` defines the wire types used in Protocol Buffers binary
 * encoding. Each type determines how the value is serialized on the wire.
 *
 * Wire types:
 *
 * - {@link VARIANT} (0): Varints (int32, int64, uint32, uint64, sint32, sint64,
 *   bool, enum)
 * - {@link I64} (1): 64-bit (fixed64, sfixed64, double)
 * - {@link LEN} (2): Length-delimited (string, bytes, embedded messages, packed
 *   repeated)
 * - {@link I32} (5): 32-bit (fixed32, sfixed32, float)
