## Features
- **Providers**: creating a compatible / custom-embedding node now registers the endpoint only — the API key is added afterwards from the node's page, like the built-in providers. The create dialogs drop the API Key / Model ID / Check fields, and `POST /api/provider-nodes` no longer accepts credentials at all, so a node can never be half-created
- **Providers**: compatible nodes now use the same model rows as built-in providers — capability badges, copy, per-model test, alias handling and the Add/Edit Model modal with vision + reasoning toggles, replacing the weaker read-only list
- **Providers**: compatible nodes get the built-in bulk toolbars: Test All / Disable / Active / Select All over connections, and Test All Models / Disable All / Active All over models, with per-row disable and a restore strip for disabled models
- **Providers**: wire the dead "Fetch Models" button on compatible nodes to the live upstream catalog, de-duplicating against already-added models
## Fixes
- **Models**: persist per-model capability assertions for custom and compatible providers and honor them everywhere — unsupported media is stripped on the chat path, `/v1/models` and `/api/models` report what the user asserted, and thinking translation follows it (asserting `reasoning:false` now actually strips thinking fields, `reasoning:true` emits them)
- **Models**: partial capability edits merge instead of overwriting, so toggling vision off no longer erases a stored reasoning assertion
- **Capabilities**: keep server-injected readers (synced catalog, user-asserted capabilities) in process-wide state — Next.js compiles startup and each API route into separate bundles with their own module instances, so a boot-time install was invisible to every request handler and the models.dev catalog contributed nothing to upstream requests since 0532f00d
- **Dashboard**: thinking-level picker and model-row suffix reflect user-asserted reasoning on compatible nodes
- **Providers**: `Default Model` is optional when adding an API key to a compatible node — the node's own model list (and the picker in the test modals) already determine what gets probed, and the built-in fallback still covers connection checks
- **Providers**: restore the `useCopyToClipboard` import dropped from the provider detail page, which crashed the route with `ReferenceError` for every provider
- **DB**: restore `getModelAliases` / `setModelAlias` / `deleteModelAlias` re-exports dropped from the `localDb` shim by 86112cee, which broke `GET /api/models` and `GET /v1/models` at import time
- **Providers**: remove dead `PassthroughModelsSection` (never passed props, superseded by the shared model rows)
- **Media Providers**: creating a custom embedding node reports that a key still has to be added, instead of claiming a key was saved; the edit dialog keeps its API Key + Check affordance since a stored key already exists there
- **Build**: self-host Inter instead of fetching it through `next/font/google` at build time — a Docker / mirrored builder with no route to `fonts.googleapis.com` failed the entire image build on `Failed to fetch 'Inter' from Google Fonts`. The seven `@font-face` rules and their `unicode-range`s copy what `next/font` emitted (a `latin`-only file would have dropped Vietnamese diacritics) and the latin subset is preloaded as before, so rendered metrics are unchanged
