fix(build): resolve TypeScript compilation errors in optimization modules

## Changes
- Export SearchStrategy enum for external module access
- Fix executeInThread function call signature with proper arguments
- Add missing useDiskBasedIndex property to OptimizedHNSWConfig defaults
- Resolve property override issues in ScaledHNSWSystem constructor
- Add explicit type annotations for S3 object parameters
- Fix ArrayBuffer type casting for compression operations

## Impact
All optimization modules now compile cleanly without TypeScript errors, ensuring type safety and proper module integration.
