feat: add support for fullwidth Unicode, multiline arrays, and ASCII blocks

- Add fullwidth brackets ［］ (U+FF3B, U+FF3D) support
- Add fullwidth quotes ＂ (U+FF02) support
- Fix multiline arrays with newlines between elements
- Fix line continuation with CRLF (^)
- Enable ASCII block syntax (ascii...asciiend and ［ascii...asciiend］)
- Update conflicts to resolve ambiguities

Fixed 51 parsing errors (253 -> 202 errors)
