🚨 Severity: CRITICAL
💡 Vulnerability: Command injection vulnerability via execSync when executing dynamically generated workspace files. The tempFile was generated dynamically in .shieldedshell/state/temp_check.js which depended on options.workspace, allowing command injection.
🎯 Impact: An attacker controlling the workspace path could execute arbitrary commands.
🔧 Fix: Replaced execSync with spawnSync from node:child_process using an array-based argument list and process.execPath to launch node, removing the shell execution risk.
✅ Verification: Ran npm run test and npm run lint. Tests all passed. Added security learning to .jules/sentinel.md.


PR created automatically by Jules for task 16650435945597728185 started by @connerkup

- Replaces `execSync` with `spawnSync` array argument list and `process.execPath` in `packages/core/src/reconcile.ts` to prevent command injection from user-controlled paths.
- Records critical learning in `.jules/sentinel.md` regarding `execSync` dangers.
