Subject: [PATCH] Replace embedded YouTube iframe by thumbnail link

Remove the inline YouTube iframe and plain link in docs/BUILD-AND-RUN.md and replace them with a linked thumbnail image for the video (q48IM4RXzTg). This reduces page weight, avoids embedding/iframe rendering issues, and improves compatibility and load performance in the docs site.
