Replaced child_process.execFile with shell: true for .cmd execution on Windows with the secure and cross-platform cross-spawn library to mitigate a CRITICAL command injection vulnerability.


PR created automatically by Jules for task 16324634064201154246 started by @fillpit

🚨 Severity: CRITICAL
💡 Vulnerability: Used `execFile` with `shell: true` to execute `.cmd` files on Windows.
🎯 Impact: This allowed command injection through shell meta-characters.
🔧 Fix: Replaced `execFile` with the `cross-spawn` package which handles Windows execution correctly without needing `shell: true`, neutralizing command injection payloads.
✅ Verification: Ran unit tests and manually verified that `safeExecAsync` uses `cross-spawn` effectively.
