Greptile Summary

This PR adds project-level globals to story enhancers by introducing a new storyGlobals property in the story context, enabling better access to global state within enhancers.

• Added storyGlobals property of type Globals to StoryContextForEnhancers interface in code/core/src/csf/story.ts
• Modified preparePartialAnnotations in code/core/src/preview-api/modules/store/csf/prepareStory.ts to include projectAnnotations.initialGlobals
• Fixed typo in deprecation comment (changed 'initiaGlobals' to 'initialGlobals')

The changes are focused and maintain backward compatibility while improving the enhancer context functionality.

Oh my, that all works quite differently than I'd initially thought...

[mrginglymus]

Hmm, there's some unfortunate mismatching of types here, where StoryContextForEnhancers seems to be used outside of what is actually passed to enhancers - as the returntype of preparePartialAnnotations, and a basis for StoryContext.
