🛡️ Sentinel: [Security Improvement] Add dangerous URL schemes to blocklist

Severity: LOW
Vulnerability: Local/network execution apps like shortcuts and terminal were allowed in TriggerKit's URL opening commands.
Impact: Potential for arbitrary application execution or sandbox escape if a malicious automation script uses shortcuts://run-shortcut?name=Malicious or terminal://.
Fix: Expanded AutomationSecurityPolicy.blockedURLSchemes blocklist to include shortcuts, terminal, ssh, telnet, vnc, ftp, smb, and afp.
Verification: Code statically analyzed to confirm addition to the set. Tests are assumed stable based on syntax check.

Poem

🐇 Hop, hop, I blocked the path,
No ssh or ftp shall pass my wrath!
shortcuts, telnet, vnc — denied,
smb and afp locked up inside.
The rabbit guards each URL gate,
No sneaky scheme shall infiltrate! 🔒
