manifest v5.54.0

✨ Minor Changes

• 466e4cf: Drop the Enable routing relic: remove the empty-state card on the Routing page so tabs and tier cards render by default, drop the complexity_routing_enabled column and its endpoints/toggle (complexity scoring is always on), delete the bulk "Disable routing" button, rename cross-page CTAs from "Enable routing" to "Connect provider", and add a Connect-providers CTA inside the model picker's empty state.
• d78828c: Surface local models (Ollama, LM Studio) as their own provider category. New auth_type: 'local' joins api_key and subscription; messages routed to local runners now carry a grey house badge in the message log, routing cards, and cost-by-model table. The Add Provider modal gets a third Local tab that appears only on self-hosted installs. Backfill migrations re-tag existing Ollama/LM Studio user_providers rows, and custom providers whose display name resolves to a canonical local runner are tagged local at insert time. Connecting/disconnecting a local provider works like the Subscription tab — click-to-disconnect flips the toggle and stops routing to it.
