_execute_stop and _execute_download no longer hand-roll ZIP extraction; all three actions now call a shared _ingest_and_link helper (ingest via ingest_nrl_zip, link the unit, drop the empty placeholder session). Every capture path produces the same clean, .rnh-parsed, percentile-aware, deduped, Leq-only session. _execute_download previously created no session at all (TODO); it now ingests like the others.
