hetao 31bf49917c feat: add unified development environment with nginx proxy
Add a root-level Makefile to manage frontend, backend, and nginx services:
- `make check` validates required dependencies (Node.js 22+, pnpm, uv, nginx)
- `make install` installs all project dependencies
- `make dev` starts all services with unified port 2026
- `make stop` and `make clean` for cleanup

Update nginx configuration:
- Change port from 8000 to 2026
- Add frontend upstream and routing (port 3000)
- Add /api/langgraph/* routing with path rewriting to LangGraph server
- Keep other /api/* routes to Gateway API
- Route non-API requests to frontend

Update frontend configuration:
- Use relative URLs through nginx proxy by default
- Support environment variables for direct backend access
- Construct full URL for LangGraph SDK compatibility

Clean up backend Makefile by removing nginx and serve targets.

# Since the ".env" file is gitignored, you can use the ".env.example" file to
# build a new ".env" file when you clone the repo. Keep this file up-to-date
# when you add new variables to `.env`.
# This file will be committed to version control, so make sure not to have any
# secrets in it. If you are cloning this repo, create a copy of this file named
# ".env" and populate it with your secrets.
# When adding additional environment variables, the schema in "/src/env.js"
# should be updated accordingly.
# Backend API URLs (optional)
# Leave these commented out to use the default nginx proxy (recommended for `make dev`)
# Only set these if you need to connect to backend services directly
