Add Quotes to CSV

Wrap every cell of a CSV (Comma-Separated Values) file in double quotes. Inner double-quotes are escaped (doubled) per RFC 4180. Switch to strings only mode to leave numbers, booleans, and empty cells unquoted.

Why force quoting

Some downstream consumers (older Excel imports, legacy SQL BULK INSERT, certain ETL tools) treat unquoted strings inconsistently — leading zeros get dropped, dashes turn into dates, leading + gets stripped. Quoting every cell makes the field shape explicit and side-steps those quirks.
