Add optional enable_compression and compression_rate fields to support token compression configuration in the AI gateway. - Add enable_compression (bool) and compression_rate (f64) to InputObject - Add builder methods with_enable_compression() and with_compression_rate() - Include fields in both send() and stream() request bodies - Fields are gateway-internal and not serialized to providers 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Rename with_enable_compression to with_compression for better API consistency - Add Compression struct with input_tokens, saved_tokens, and rate fields - Add optional compression field to SendResponse for root-level compression data
- Add test for response with compression field deserialization - Add test for response without compression field - Add test for InputObject with_compression builder method
