The modify/src/channels/whatsapp.ts patch in the add-voice-transcription
skill was missing the registerChannel() call and its registry import.
When the three-way merge ran, this caused the WhatsApp channel to silently
skip registration on every service restart — messages were never received.
Added the missing import and registerChannel factory with a creds.json
guard, matching the pattern used by the add-whatsapp skill template.
