feat: add opencode plugin with router integration and TypeScript definitions

- Implemented `createRouterAgentPluginFn` in `src/opencode.ts` to create a plugin that interacts with the router and filters routes based on metadata tags.
- Added support for executing routes with error handling and response formatting.
- Updated `rollup.config.js` to include build configurations for `opencode.js` and `opencode.d.ts`.
