halo model switch

Point an alias at a model: in place, or with –canary as a guardrailed traffic rollout

<model> is a provider model id, optionally prefixed <provider>/ (e.g. bedrock/anthropic.claude-opus-5-5). Without –canary the route is edited in place (halos.yaml models.<alias> in simple mode). With –canary it writes a traffic-axis Rollout from the rollout preset plus its experiment.

Usage
