📦 build(server): self-contained dev/start entry for @lobechat/server

- add pnpm dev (vite-node watch, loads repo-root .env via new src/hono/dev.ts)
  and pnpm start (node dist/standalone.js) scripts
- move viteNodeServer/viteHonoBuild configs from scripts/ into apps/server
- root dev:hono:server now delegates to pnpm --filter @lobechat/server dev
