What changed in v0.20.1

Toolset configuration accepts `default`; pull-request review writes use one method-based tool.

Release binary or container v0.20.1; requires a compatible MCP client and GitHub credentials. Feature-specific opt-ins and permissions apply.

Fixed and improved

Combine `default` with extra toolsets, such as `default,discussions`; unknown toolsets are ignored. The read-only environment variable mapping is fixed.
