AI Summary

This core release addresses stability issues with AI reasoning signatures and refines the routing logic for Anthropic raw-body passthrough to prevent incorrect payload forwarding on multi-family providers.

Key Highlights

Fix for encrypted reasoning signature handling when unsupported
Improved routing logic for Anthropic raw-body passthrough

Full Release Notes

## Core Release v1.8.4

- fix: strip the encrypted reasoning signature when the upstream reports the field as unsupported (e.g. Bedrock Converse replaying a Claude signature onto a non-Anthropic model after a mid-conversation model switch), extending the existing unverifiable-signature fail-soft
- fix: clear Anthropic raw-body passthrough based on the resolved provider and model pair, so non-Claude models on multi-family providers (Vertex, Azure, Bedrock Mantle) convert the request instead of passing the Anthropic payload through
