Conversation
Claude Code 2.1.284 ships Sonnet 5.5 and points its `sonnet` alias at it, but styal's Claude catalog does not list the model, so the picker cannot offer it. Add a Sonnet 5.5 entry gated on Claude Code 2.1.284 with a NEW badge, and a profile matching the CLI's model catalog: low through max effort with medium as the default, ultracode, and a selectable 1M context window using the same `[1m]` suffix as Sonnet 5. Move Sonnet 5 into Legacy models while keeping its `sonnet` alias for older Claude Code versions, and replace it in the pre-catalog current-model list.
