Module anthropic 

Anthropic route handler — POST /v1/messages

Intercepts Anthropic API requests, runs the SHIFT optimization pipeline on the payload (extracting and transforming images), records stats with full per-image token savings, and forwards to the real Anthropic API.

The CPU-intensive optimization runs on a blocking thread to avoid starving the tokio event loop.
