Module context: dmel_mitochondrial_degradosome (Suv3 with PNPase).
Deep research: Suv3-deep-research-falcon.md (falcon).
Decisions: all accepted except DNA helicase activity (ISS from human SUPV3L1), marked as
over-annotation since fly Suv3 acts on mitochondrial RNA and is not nuclear. Two core
functions: degradosome RNA helicase in decay, and PNPase-independent precursor processing.
