Goose 1.50.0 rips out its own auto model routing

Block stripped fast model routing and the managed model registry from goose 1.50.0, pulling two features that used to pick models for users automatically.

That matters for anyone running goose in scripts or automated pipelines, where the router used to pick a model without asking. Those setups now need a model pinned by hand, since the layer that chose one automatically is gone.

Goose 1.50.0 also adds GPT-6 Astra support and tool calling for goose-agent. It splits the ACP client and the acp binary into their own npm packages. Other agent harnesses can now speak Agent Client Protocol without installing the rest of goose.

The release carries four security fixes. HTTPS is now required for Snowflake connections, and CLI session naming is bound to a trusted path. Subagent platform guards are enforced, and permission revocations persist across managers.

The release notes don't say why the registry got cut. Maybe it was a maintenance burden, a trust problem, or a routing accuracy issue that never worked well in practice.
