Full Release Notes

## What's new

- Added `JevClassifier`: routes with TypeSafe's Jev decision model instead of an LLM. The registered agents become a typed `choice` question, and Jev returns the chosen agent plus a calibrated confidence, billed on input tokens only. Uses the built-in `fetch`, no new dependencies. See the [docs](https://2fastlabs.github.io/agent-squad/classifiers/built-in/jev-classifier) (#699)
- MCP protocol 2026-07-28 support via `@modelcontextprotocol/client` v2 (#642)
- Streamable HTTP transport in `MCPToolProvider` (#639)
- Tool-UI (widget) support in `GroundedAgent`, forwarded through the orchestrator (#605, #599)
- MCP tool-UI passthrough in `MCPToolProvider` (#597)
