Added `__attrs_post_init__` validation using the new restricted pattern `^[\\t !#$%&()*+\\-.,/:;<=>?@\\[\\\\\\]^_{|}~]$` (printable non-alphanumeric ASCII only, excluding alphanumeric chars and control chars like CR/LF). Also added a module-level `_CSV_DELIMITER_PATTERN` regex constant and `import re`. The `Base.to_api()` serialization automatically includes `delimiter` when set and excludes it when `None`. No changes to `__init__.py` needed (ExportSettings was already exported).",
