LibTextCodec: Add streaming decoder Introduce a StreamingDecoder wrapper that lets callers feed bytes to a Decoder one chunk at a time. It buffers any incomplete trailing byte sequence at the end of a chunk and prepends it to the next chunk, so a multi-byte code point split across a chunk boundary is decoded correctly once the next chunk arrives. To support that, add an incomplete_tail_length() virtual on Decoder returning the number of trailing bytes that form an incomplete sequence per the Encoding Standard's decoder handler byte ranges, with overrides for UTF-8, UTF-16BE, UTF-16LE, GB18030, Big5, EUC-JP, ISO-2022-JP, Shift_JIS, and EUC-KR. The default implementation returns 0, which keeps single-byte legacy decoders correct. This is the foundation for the upcoming incremental HTML parser, which needs to decode network response bodies as they arrive. 2026-04-27 15:00:25 -03:00			`class StreamingDecoder;`
