/**
 * server/index.ts — LEGACY STATIC-ONLY ENTRY POINT
 *
 * @deprecated This file is NOT used in production or development.
 *
 * The real application server is: server/_core/index.ts
 *   - Registers tRPC router (/api/trpc)
 *   - Registers OAuth routes (/api/oauth/callback)
 *   - Runs Vite middleware in development
 *   - Serves pre-built static assets in production (dist/public)
 *   - Seeds default agents on startup
 *
 * This file was the original minimal static server created before
 * tRPC integration. It has NO tRPC routes, NO OAuth, NO seed logic.
 *
 * Build entrypoint (tsconfig/vite.config) → server/_core/index.ts
 * Dockerfile CMD → node dist/index.js (compiled from _core/index.ts)
 *
 * ⚠️  DO NOT add business logic here.
 *     DO NOT run this file directly in production.
 *     It is kept as a historical artefact and may be removed in a future
 *     cleanup phase (see todo.md Phase 17 — technical debt).
