fix: 🛡️ Sentinel: [CRITICAL] Fix SSH command injection

[Hardonian]

🚨 Severity: CRITICAL
💡 Vulnerability: Command Injection in SSH Remote Execution where child_process.exec was evaluating local shell metacharacters from concatenated command arguments.
🎯 Impact: Local execution of arbitrary commands on the system running the CLI/agent.
🔧 Fix: Replaced exec with execFile and passed SSH arguments as an array, bypassing local shell parsing.
✅ Verification: Tested via the control-plane test suite and verified manually by executing payload-injected shell commands (test-exec-inject2.ts), confirming that execFile prevented the evaluation of shell control characters.
