- Move cache_control from request root (ignored by API) to per-block placement on last system block and last tool definition - Change system prompt time format to date-only for better cache stability - Add builtin datetime tool for precise timestamps (cron, memory, etc.) - Add atMs past-time validation in cron handleUpdate (was only in handleAdd) - Update cron description to guide model to use datetime tool first
