fix(delete): count recursive missing-arg removals per entry (#290)

A non-empty --delete-missing-args directory removed under --force/--delete
now has its contents deleted entry-by-entry through the budgeted walker, so
every deleted file/dir counts toward --max-delete exactly like rsync (a
capped run leaves the remaining entries and exits 25).
