Switchboard — Stream Deck plugin (developer guide)

A macOS Stream Deck plugin (public name Switchboard, by Moving Average Labs). Built with the Elgato SDK v2 (TypeScript/Node). The plugin UUID is com.movingavg.switchboard (renamed from the legacy com.johnknox.safarijump). Don't change it casually — installed buttons reference it, so a change orphans configured keys unless migrated. scripts/rename.sh performs such a migration (it rewrites the UUIDs in the Stream Deck profile store so settings survive); see that script before ever renaming again. Sixteen actions today (the manifest is the source of truth — scripts/make-hero.py reads it).
