### Expected Behavior

Cron jobs should be strictly limited in privilege and subject to robust prompt injection scanning. All tool invocations by cron jobs should require user approval unless explicitly whitelisted. 

### Actual Behavior

Cron jobs execute with nearly full agent privileges, bypassing approval and scanning if malicious instructions are phrased in natural language.

### Affected Component

Tools (terminal, file ops, web, code execution, etc.)

### Messaging Platform (if gateway-related)

N/A (CLI only)

### Operating System

Ubuntu 22.04

### Python Version

3.13.7

### Hermes Version

v0.8.0(v2026.4.8)

### Relevant Logs / Traceback

Bypass success rate: 6/7

Full attack prompt scan result: PASSED (no threats detected)
VULNERABILITY CONFIRMED: This prompt passes all 10 threat patterns
but instructs the agent to read .env + config.yaml and exfiltrate them.
In cron mode, all tool calls are auto-approved (approval.py:610-611).
