/**
 * Google Protobuf binary wire format (v2/v3 compatible).
 * Tag: varint (field_number << 3 | proto_wire_type). Sub-messages: LEN-prefixed.
 * Uses buffer stack for nested struct length-prefixing.
 * Read side accepts optional field schema map (field_id → DpWireType) for accurate type recovery;
 * without schema, best-effort mapping from proto wire type (3-bit) to DpWireType.
