fix: clear utf8 remainder on base64 failure and allow malformed decode

Browse source 
Address CodeRabbit review feedback:
- Clear _utf8Remainder when base64 decode fails to prevent stale bytes
  from corrupting subsequent chunks
- Add allowMalformed: true to utf8.decode() so malformed bytes become
  U+FFFD instead of throwing FormatException and losing the entire chunk
