🛡️ Sentinel: [security improvement] Prevent command injection by replacing shell wrappers in dockerPrune

🚨 Severity: MEDIUM
💡 Vulnerability: The dockerPrune function used a hardcoded /bin/bash -c shell wrapper to execute docker system prune -f 2>&1. While the string was static, using shell wrappers for simple executable execution is a security anti-pattern that exposes the application to command injection if arguments are ever dynamically generated.
🎯 Impact: Using direct executable path execution via /usr/bin/env rather than /bin/bash completely mitigates the risk of command injection in the case of future modification.
🔧 Fix: Removed /bin/bash from process.executableURL. Instead used /usr/bin/env executing docker with explicitly defined arguments ["system", "prune", "-f"]. The shell redirection 2>&1 was natively managed using the existing Pipe() setup.
✅ Verification: Ensure the app builds and that the "Prune Docker" action still works efficiently and outputs logs correctly.
