- text_parser.go now uses the shared DefaultTextCodeDelimiter from
delimiter.go instead of a private duplicate that could drift silently.
- Fix the golden-regeneration comment: no generator script is committed;
the baseline is reproducible from the golden's meta block.
- Add TestTextParser_AdjacentDelimiters pinning the documented adjacent-
delimiter behavior (Go drops the standalone second delimiter) so a
future silent change in splitCapturingDelims is caught.
