/**
 * LOCAL ambient stub for OpenCode's plugin API — not the vendor's types.
 *
 * `@opencode-ai/plugin` is resolved by OpenCode when it loads the plugin; it
 * is not a dependency of this repo. This declares only the surface
 * auto-model-router.ts uses, so the plugin is type-checked with the rest of
 * the tree (tsconfig.all.json). The real types live in the package OpenCode
 * installs under ~/.config/opencode/node_modules/@opencode-ai/plugin; treat a
 * change here as a claim about that API that only a live session confirms.
