Update Provider Models

This handles the grunt work of adding new AI model IDs or removing obsolete ones across the AI SDK codebase. It's built for maintainers who need to update type definitions, documentation tables, example files, and tests when providers ship new models or deprecate old ones. The workflows are thorough about exact matching (since model IDs like "grok-3" and "grok-3-mini" are easy to confuse), respecting sort order in unions and arrays, and tracking down every reference location through grep searches. It won't touch changelogs or codemods, and it processes multiple model updates sequentially to avoid chaos. If you maintain an SDK with provider integrations, this is the kind of repetitive cross-file update that benefits from automation.
