Initial commit: ein-ai-proxy

Anthropic-compatible API proxy that routes requests to multiple
providers (Anthropic, Z.ai/GLM-4.7, DeepSeek V3.2) based on
model name. Zero dependencies, SSE streaming, bearer token auth.

Designed to run behind Caddy/nginx on a home server, enabling
Claude Code and Roo Code clients to connect from anywhere.
