- Add google/wire; generate wire_gen.go from wire.go injector - Move all constructor wiring out of main.go into providers.go / wire.go - Export recognition.IngredientRepository (was unexported, blocked Wire binding) - Delete units/cuisine/tag registry.go files (global state + unused NameFor helpers) - Replace List handlers with NewListHandler(pool) using COALESCE SQL queries - Remove units/cuisine/tag LoadFromDB from server startup; locale.LoadFromDB kept (locale.Supported is used by language middleware on every request) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
