HydraFusion stops making you pick a model (and adds a “Max” mode)

Copilot’s multi-model orchestrator (still research preview) refreshed its pool — Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna — drafts on medium effort, reviews on high. Cascade gets a judging step; Critique can tool-snoop the workspace with parallel critics. New HydraFusion Max is the “go deep” button. Lives in VS Code, the Copilot app, and Copilot CLI.
