feat(cli): ludic deps --writes warns about writes through a local alias

A local bound straight from another module's global (let t =
thing_cur), or from such a local, is followed within its function, and
a write through its field or element is listed as a warning after the
counted writes. A reference from a function's result is not followed.
Reseed.
