Improve 7ya platform sync content reach

[vepretski]

Motivation

• Improve cross-platform reach for the 7ya.io influencer workflow by adding platform-specific sync guidance and broader channel coverage.
• Ensure every generated asset includes metadata (sync_role and reach_action) so manual operators and automation have explicit intent for each post.
• Make the campaign generator produce a synchronized Israeli-focused distribution plan and keep 7ya.io as the canonical CTA and source of truth.

Description

• Expanded the channel set in script/personal-brand-booster.ts to include TikTok, YouTube Shorts, Facebook, Threads, Telegram, WhatsApp Broadcast, Viber and others, and added syncRole and reachAction fields to each channel entry.
• Updated generation logic to inject sync_role and reach_action into every platform file and to produce a new platform-sync-playbook.md, a richer campaign-plan.json, updated daily-posting-plan.md, and an expanded repurposing-map.md.
• Adjusted brief metadata (personal_brand_angle and audience) and strengthened validation checks in the script to require sync_role and reach_action for each generated file.
• Regenerated artifacts under outputs/personal-brand-booster-yb-2026/ (added bilingual files such as en-facebook-post.md, he-telegram-broadcast.md, en-youtube-shorts-script.md, platform-sync-playbook.md, etc.) and updated the script artifact-count log.

Testing

• Ran the generator with bun run script/personal-brand-booster.ts --source ./input/igor-vepretski-yisrael-beiteinu-campaign.md --lang both --out ./outputs/personal-brand-booster-yb-2026 and it completed successfully producing artifacts.
• Verified validation by running jq -e '.status == "pass"' outputs/personal-brand-booster-yb-2026/validation.json which returned true.
