<issue_title>[q] issue-monster: switch to codex engine and add red team safety check</issue_title>
<issue_description>## Changes

Updates to the Issue Monster workflow based on #17064 and the /q request from @pelikhan.

1. Switch engine from copilot to codex

Changed engine.id from copilot to codex while keeping the same gpt-5.1-codex-mini model:

engine:
  id: codex
  model: gpt-5.1-codex-mini

2. Add Red Team Safety Check section

Added a ## 🔴 Red Team Safety Check section to the agent prompt that instructs the Issue Monster to silently skip any issue that appears malicious or dangerous, including:

• Prompt injection attempts
• Requests to exfiltrate data/credentials/secrets
• Exploit/vulnerability/penetration testing requests
• Social engineering tactics (false urgency, impersonation)
• Requests to bypass security policies or access controls

When an issue is flagged, the agent skips it without commenting (to avoid engaging with malicious content). If all candidates are flagged, it calls noop with a safety message.

Validation

✅ issue-monster compiled successfully with no errors or warnings.

• Fixes [agentics] Issue Monster failed #17064

🎩 Equipped by Q for issue #17064
