// std/fs:read-lines — the effect shape, against a real data file.
// The event owns the buffer (created and freed inside its own scope;
// `! line` handlers borrow only DURING the read) — resource-safe without
// phantom ceremony. Was a TODO ("fs.read_lines not implemented") from the
// array-shape era; the effect shape IS the implementation.
