How the feature works? / How did you fix the issue?

(Screenshots, videos, or GIFs, if applicable)

Files Created:
types.ts (new file)

• Defined CurrentAppState interface that types the global currentState variable

• Contains editor (KetcherEditor) and options (OptionsState) properties

• Eliminates implicit any types for the global state

  copyImageToClipboard.ts (converted from .js)

• Renamed file extension from .js to .ts

• Added return type annotation Promise to function

• All variables have explicit types:

• state: CurrentAppState - types the global state

• editor: KetcherEditor - imported from ketcher-core

• options: OptionsState - imported from store.types

• struct: Struct - return type of structSelected()

• errorHandler: ((message: string) => void) | null - from editor

• structStr: string - serialized structure

• generateImageOptions: GenerateImageOptions - from ketcher-core

• image: Blob - return type of generateImage()

• e: unknown - catch block error (safer than any)

Added global Window interface declaration to properly type global.currentState
Imported GenerateImageOptions from ketcher-core for type compatibility
Added null check for errorHandler before calling
Files Removed:
copyImageToClipboard.js (original JavaScript file)
