Add Igor Vepretski platform sync playbook (7ya.io)

[vepretski]

Motivation

• Centralize Igor Vepretski's public presence and route all platform traffic and conversions to https://7ya.io.
• Establish consistent identity, messaging, and CTA conventions across owned and rented platforms to prevent profile drift.
• Provide an operational framework to increase measurable traffic, conversions, and attribution accuracy.

Description

• Add IGOR_VEPRETSKI_PLATFORM_SYNC.md which defines the canonical (own) and distribution (rented) layers and the source-of-truth model.
• Define brand sync standards including identity, bio variants, voice/messaging, and a managed link architecture with UTM conventions and 7ya.io path patterns.
• Add a Publishing OS with weekly cadence, content derivative matrix, platform-specific execution specs, and a 30/60/10 content mix.
• Include governance and roles, operations checklists (initial alignment, weekly ops, monthly reviews), KPI framework, incident playbooks, and a clear "Definition of Done."

Testing

• No automated tests were run for this documentation-only change.
