fix(scripts): list the chokepoint seam directory inside SCAN_FILES

A SEAM_DIR constant read to bare-root-worklist as a new invisible bare-root
population; the gate already declares every file it reads, one by one, in
DECLARED_WATCH_HINTS, so the directory is spelled inline as the three
driver files are.
