Refactor subagent model configuration from nested modelConfig object to a simple model string field for better UX and clarity.
Changes:
- Replace modelConfig object with model string in SubagentConfig interface
- Add model-selection.ts utility for parsing and validating model selectors
- Support 'inherit' keyword and bare model IDs (e.g., 'glm-5', 'claude-sonnet-4-6')
- Maintain backward compatibility by parsing legacy modelConfig frontmatter
- Update validation to reject cross-provider authType-prefixed selectors
- Update SDK types (TypeScript and Java) to reflect new schema
- Add comprehensive tests for model selection and validation
- Update documentation with model selection examples
Breaking changes:
- modelConfig.frontmatter field deprecated in favor of model field
- Cross-provider model selectors (e.g., 'openai:gpt-4') not supported for subagents
