CSV → JSON Schema

Walk every row of a CSV (Comma-Separated Values) file and emit a Draft-07 JSON Schema describing the per-row object. Types are inferred by sampling all non-empty values: integer, number, boolean, otherwise string. Columns with any empty cells get a nullable union; fully-populated columns are added to required.
