Identity function for typing an array of features:

const features = defineFeatures([musicModule, moderationModule]);

Features are explicitly registered via loadFeatures in createBightApp() — they are not auto-discovered.
Commands and handlers from features merge into the app’s main registry during startup.
Duplicate command names across features are detected and reported with the feature’s name for context.
