Fix TypeScript compilation errors

- Added missing imports for ToolResponse and z in index.ts
- Added missing imports for WindowInfo and TargetApplicationInfo in list.ts
- Fixed type casting for ImageCaptureData in image.ts
- Added proper return type annotations to handlers
- Fixed content array metadata type to Record<string, unknown>
- Added const assertions for all 'text' type literals
- Fixed return types for helper functions in list.ts
- Added minItems and maxItems to JSONSchema interface

All TypeScript compilation errors resolved
