feat: implement plugin-based resource architecture

- Create src/resources directory for resource plugins
- Move simulator resource to plugin-based structure
- Update build plugin to scan and generate resource loaders
- Add generated-resources.ts to auto-load resources at build time
- Update resource registration to use dynamic loading
- Resources now follow same configuration-by-convention pattern as tools
- Add comprehensive tests for resource plugins and loading

This enables dropping *.ts files in src/resources to automatically register
new MCP resources without manual imports or registration code.
