- Add opus[1m] to the default model fallback list (Claude Opus 1M context) - Drop version numbers from Sonnet/Opus/Haiku descs so they auto-follow upstream version bumps (4 -> 4.6/4.7 -> future) without code churn - Skip sonnet[1m] (needs extra usage) and haiku[1m] (subscription has no permission) since the CLI accepts the syntax but usage is gated Co-authored-by: 张彧 <aaron@mac.tail449498.ts.net>
