    : string

Extract all valid dot-separated paths from an object type. Produces paths like "name" | "address.city" | "address.postcode". Stops at leaf types (string, number, boolean, null) and arrays. Returns string for wide types (object, Record, unknown). Handles optional/nullable fields by unwrapping T | undefined.
