🛡️ Sentinel: [HIGH] Fix command injection in directory picker

[devdudumuniz]

🚨 Severity: HIGH
💡 Vulnerability: Command injection in _native_dir_picker due to unescaped user inputs (title and initialdir) being directly interpolated into PowerShell and AppleScript strings.
🎯 Impact: A malicious user could provide crafted input strings that break out of the string literal and execute arbitrary commands on the host machine.
🔧 Fix: Added proper escaping for single quotes in PowerShell ('') and double quotes/backslashes in AppleScript (\" and \\).
✅ Verification: Ran pytest pysus/tests/ to ensure no regressions. Verified locally that payload execution is stopped and tests pass.
