fix(cron): rewrite cloud-incompatible prompt instructions (#378)

Health Monitor prompts say 'Check Ollama is responding' but run
on cloud models that cannot reach localhost. Instead of just
warning the agent, rewrite the instructions to cloud-compatible
equivalents the agent can actually execute.

Changes:
- Add import re
- Add _CLOUD_INCOMPATIBLE_PATTERNS: regex pairs (pattern, replacement)
- Add _rewrite_cloud_incompatible_prompt(): rewrites localhost/Ollama
  references to 'use available tools to check service health'
- Wire into run_job() after resolve_turn_route()

Closes #378
