test(cron): add tests for cloud-context warning injection

Fixes #378, Closes #456

When a cron job runs on a cloud endpoint but its prompt references
local services (Ollama, localhost ports, etc.), inject a SYSTEM NOTE
telling the agent it cannot reach localhost so it reports the
limitation instead of wasting iterations on doomed connections.
