giles 8cdebbe305 apl: ⍸ where — monadic indices-of-truthy + dyadic interval-index ...

- apl-where (monadic): ravel scan, filter non-zero, +⎕IO offsets
- apl-interval-index (dyadic): count of breaks ≤ y; broadcasts over
  scalar or vector Y
- Wired into apl-monadic-fn / apl-dyadic-fn cond chains
- +10 pipeline tests covering both arities, ⎕IO offsetting, edge cases
  (empty mask, all-truthy, y below/above all breaks)
- pipeline 109/109
