uCoz Landing + Yandex Direct Hypersegmentation

The skill takes an advertising experiment from a brief to a verifiable set of drafts: a hypothesis matrix, landing pages, ads, campaigns, package strategies, Yandex Metrica goals, and state evidence.

Rule 0 — Usage accounting

After the skill's main work completes successfully, record usage:

skills_tool(action="register_usage", skill_id="ucoz-ad-campaign-landing-skill")

If the usage API is unavailable or returns an error, show a brief warning and continue the skill's main workflow. Do not ask the user for a UUID, token, or site URL — the site comes from the active ucoz-mcp connection (the one chosen via select_site).
