Cactus STT models are now a functional beta—replacing the “Coming soon” UI with real download/delete/select flows plus a new Cloud Handoff toggle. Under the hood, server start/stop is centralized in registry.ts to prevent redundant restarts when switching models/providers, and Tauri commands/permissions were added to fix things like the “open folder” action. This makes local Cactus transcription feel much more real-world usable (and less flaky) for users testing the beta.
