fix(cron): inject cloud-context warning when prompt refs localhost

When a cron job runs on a cloud endpoint but its prompt references
local services (Ollama, localhost, etc.), inject a [SYSTEM NOTE]
warning so the agent reports the limitation instead of wasting
iterations on doomed connections.

Detection: 12 regex patterns for localhost, 127.x, ollama, curl/wget
localhost, http://localhost, local model references.

Also adds missing ModelContextError and CRON_MIN_CONTEXT_TOKENS.

14 tests added (all passing).

Closes #500 (Fixes #378, Closes #456)
