giles 9c5a697e45 datalog: dl-clear-idb! helper (208/208) ...

Wipes every rule-headed relation (the IDB) — leaves EDB facts and
rule definitions intact. Useful for inspecting the EDB-only
baseline or for forcing a clean re-saturation.

  (dl-saturate! db)
  (dl-clear-idb! db)        ; ancestor relation now empty
  (dl-saturate! db)         ; re-derives ancestor from parents

2 new api tests verify IDB-wipe and EDB-preservation.
