Add 7ya.io video intake and backstage promotion checklist

[vepretski]

Motivation

• Add a new video intake entry to ensure this asset is processed through the 7ya.io control plane and consistent CTA paths.
• Capture an explicit operator command phrase so campaign operators and automation can detect and prioritize this upload.
• Add short-form/backstage distribution and UTM tracking guidance to align the asset with existing campaign workflows.

Description

• Inserted a new Video Intake section for https://youtu.be/lxDBBHCOqdI?si=lOQr5gZr3DY7uDfO in IGOR_VEPRETSKI_PLATFORM_SYNC.md.
• Recorded the exact operator command phrase COMMAND: PROMOTE OUTONOMIOSLY BACKSTAGE! and guidance to treat the upload as a backstage-distribution trigger that routes actions to https://7ya.io with the Manage 7ya.io CTA.
• Added actionable checklist items for transcript extraction, identifying 3–5 strong backstage moments, creating short-form cuts (YouTube Shorts, TikTok/Instagram Reels) plus an X backstage thread, and applying 7-day UTM tracking for conversion analysis.

Testing

• Ran repository inspection and diff checks with git status --short, git diff -- IGOR_VEPRETSKI_PLATFORM_SYNC.md, and file preview via nl -ba IGOR_VEPRETSKI_PLATFORM_SYNC.md | sed -n '110,200p', and each command completed successfully.
• Verified the modified file contains the new intake section and checklist items as expected by inspecting the diff output, which showed the inserted lines.
