#9809 improvement(changelog): cover meaningful product updates through v0.9.54

Summary

• Add five concise changelog stories covering meaningful changes through v0.9.54: Search actions and shortcuts, Chrome and desktop, image-to-video, saved connections, and workflow controls.
• Date the retrospective entries to October 30, November 4, November 7, November 10, and November 11. Label each change’s release and retain a current updated date.
• Include reviewed product imagery and original monochrome illustrations. Correct the older sign-out announcement and the Video Generator’s Reference Image label.
• Preserve existing article URLs, publication dates, and RSS identities. Leave routine implementation work and unverified rollouts in technical history.
