Fixed a critical command injection vulnerability in packages/core/src/reconcile.ts.

The reconcile function used execSync with a dynamically generated shell command that included a workspace path. If the workspace path contained shell metacharacters, this could lead to arbitrary command execution on the host machine.

This has been remediated by replacing execSync with spawnSync, which accepts an array of arguments, thereby avoiding shell interpretation altogether. In addition, the use of node via the $PATH has been replaced with process.execPath to prevent potential execution tampering via modified environment variables.

A Sentinel journal entry documenting this learning was also added.
