📝 Walkthrough

Walkthrough

The changes refactor how story names are resolved and code snippets are generated in the component manifest generator. Story iteration now uses both the export key and story object, with the story's runtime name taking precedence when available. Test expectations are updated to reflect the new naming format.

Changes

Cohort / File(s)	Summary
Component Manifest Generator Refactor code/renderers/react/src/componentManifest/generator.ts	Changed story iteration from using storyName alone to using [storyExport, story] pairs. Name resolution now prioritizes story.name with fallback to storyNameFromExport(storyExport). Updated getCodeSnippet and error handling calls to pass storyExport instead of storyName. Added import for storyNameFromExport function.
Generator Test Fixture Updates code/renderers/react/src/componentManifest/generator.test.ts	Updated test fixture expectations to use space-separated story names ("Logged In", "Logged Out") instead of camelCase variants.
