Update README and fix UploadQueueWidget re-rendering

Added a call-to-action link and updated the main screenshot in README.md. In UploadQueueWidget.tsx, set a dynamic key on the Virtuoso list to ensure proper re-rendering when tasks or collapsed state change. Minor cleanup to computeItemKey usage.
