…ef URLs The previous PR (anomalyco#12112) added `.meta({ $ref: 'https://models.dev/...' })` to model fields for editor autocomplete, but `@standard-community/standard-openapi` has a bug in `convertToOpenAPISchema` where it converts external $ref URLs into local `#/components/schemas/{lastSegment}` references. For `https://models.dev/model-schema.json#/$defs/Model`, this extracted just 'Model' and created `#/components/schemas/Model` - colliding with the existing runtime Model object schema. This caused config model fields (which should be strings like 'anthropic/claude-4') to be typed as the full Model object in the generated SDK. The patch strips external $ref URLs (containing '://') and preserves the remaining schema properties (like `type: 'string'`) instead of converting them to broken local references. Verified: SDK generation + typecheck pass, all model fields correctly typed as string.

Pull request overview
This PR updates OpenCode’s configuration JSON Schema generation to reference the external models.dev schema for model fields, enabling editor autocomplete for valid model IDs while ensuring OpenAPI generation doesn’t break on external $refs.
Changes:
- Introduces a shared
ModelIdZod schema annotated with an external$reftohttps://models.dev/model-schema.json#/$defs/Model. - Switches config fields (
model,small_model,agent.*.model,command.*.model) to useModelId. - Adds a Bun patch for
@standard-community/standard-openapi@0.2.9to handle external$refduring OpenAPI conversion.
