- Replaced unsafe `execSync` usage with array-based `spawnSync`. - Used `process.execPath` instead of a string `"node"`. - Handled non-zero exit status cleanly for `spawnSync`. - Added journal entry for command injection learning.

🚨 Severity: HIGH
💡 Vulnerability: Use of string-based
execSyncfor node syntax checking (execSync(\node --check "${tempFile}"`)) allows for potential command injection iftempFilepath can be manipulated. 🎯 Impact: If thetempFilepath can be manipulated by an attacker, they can execute arbitrary shell commands. 🔧 Fix: ReplacedexecSyncwith array-basedspawnSyncand usedprocess.execPathinstead of relying on the systemnodeexecutable. This completely neutralizes command injection for this execution pathway. ✅ Verification: Rannpm test -w @shieldedshell/coreandnpm run lint` successfully.PR created automatically by Jules for task 15272701783144956404 started by @connerkup
