…o plugin SDK - Add optional getAuth to PluginInput for plugin auth credential access - Add route hook (object form with prefix) for plugin HTTP routes - Add model.select hook for sub-model resolution (e.g. workflow models) - Add AuthLoaderResult type with optional getModel for auth loaders - Exclude route from trigger type constraint (not a callable hook) - Add tests for all new types and trigger constraints All additions are backward-compatible with existing plugins.

Issue for this PR
Extends the plugin SDK to support plugins that need auth access, HTTP routes, and model sub-selection. Part of the work to extract GitLab DAP workflow model support into a standalone plugin, keeping opencode core free of provider-specific code.
Type of change
What does this PR do?
Adds four backward-compatible type extensions to the plugin SDK (
packages/plugin/src/index.ts):getAuth?onPluginInput— lets plugins retrieve stored auth credentials (OAuth tokens, API keys) for a provider. Plugins previously had no way to access auth state.AuthLoaderResulttype — replaces untypedRecord<string, any>return ofAuthHook.loaderwith a type that optionally includesgetModel, so auth loaders can provide custom model creation logic.routehook onHooks— accepts either(app) => void(existing) or{ prefix: string; handler: (app) => void }(new). Object form lets plugins specify a URL prefix so routes mount at/plugin/<prefix>/.model.selecthook onHooks— called when a model is selected. Plugins can resolve sub-models (e.g. a workflow model needing further discovery). Takes{ providerID, modelID }, mutates{ subModel?, displayName? }.Also excludes
routefromPlugin.trigger()type constraint inpackages/opencode/src/plugin/index.tssinceroutecan be an object, not a callable function.All changes are additive — existing plugins compile and work without modification.
