Enhance capture ownership management in Worker.worker.ts

- Introduced captureBaseOffset and captureOwnerCounts to manage ownership changes across a defined capture window.
- Updated the processing logic to spread ownership updates more effectively, improving tile reveal calculations during game updates.
- Cleared captureOwnerCounts at the start of processing to ensure accurate tracking of ownership changes.
