dream: periodic memory consolidation

Hotovo. Jediná změna: v `memory/MEMORY.md` jsem upřesnil popis `nanobot-version-check` cron jobu podle nové historie (porovnání verzí, notifikace přes Telegram, upgrade příkaz). Ostatní soubory už obsahovaly relevantní fakta (čeština v `USER.md`, cron detaily v `MEMORY.md`), takže nebylo potřeba nic přidávat ani přesouvat. Žádný nový skill nevznikl — jde o jednorázovou konfiguraci cron jobu, ne opakovatelný workflow.
