fix(cron): inject cloud-context warning when prompt refs localhost (#468)

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.

Fixes #378, Closes #456.

## Changes
- cron/scheduler.py: Added import re, _LOCAL_SERVICE_PATTERNS (12 patterns),
  _detect_local_service_refs(), _inject_cloud_context(). Injection in run_job()
  after cloud endpoint detection.
- tests/cron/test_cron_cloud_context.py: 19 tests

## Detection patterns
localhost:PORT, 127.x.x.x:PORT, 0.0.0.0:PORT, ollama, curl localhost,
wget localhost, http://localhost, https://127.x, check ollama,
connect local, hermes gateway local

Closes #468.
