We have upgraded the chat interface to play source material videos directly within a modal dialog, eliminating the need to jump to a new browser tab. Additionally, if a student explicitly requests to watch a video, the system now promotes the relevant media to its own dedicated block above the documents and pages for better visibility. This improves content discovery and keeps the learning workflow uninterrupted. In-app playback is better

Implemented in-app YouTube playback for a more seamless chat experience - subh05sus/sparkmentor
