/// Encode a session id into a filesystem-safe file name.
///
/// Session ids are usually UUIDs, but this prevents path-separator injection
/// when the id comes from an untrusted source (e.g. a library caller passing an
/// arbitrary resume id). Every character that is not an ASCII letter, digit,
/// hyphen, or underscore is replaced with `-`.
