v3.3.0a1

argo-proxy 3.3.0a1 — Dev-Proxy Mode (Pre-release)

Adds --dev passthrough mode on top of the gateway migration from 3.3.0a0.

What's new

• --dev mode: transparent reverse proxy — all API requests forwarded to ARGO upstream without model resolution or format conversion
• Supported routes: /v1/chat/completions, /v1/responses, /v1/messages, /v1beta/models/<path>, /v1/embeddings, /v1/models
• Streaming (SSE) and non-streaming both supported
• Skips model registry init for faster startup
• Auth warning detection still active
• 22 unit tests for dev-proxy handlers

Changes since 3.3.0a0

• dev_proxy.py (new): per-endpoint passthrough handlers
• transport.py: added raw_client() public method
• app.py: dev-mode route wiring, skip registry init
• cli/parser.py: --dev flag no longer hidden
