Miggo AIRoot Cause Analysis

The vulnerability stems from the Error.prepareStackTrace handler in setup-sandbox.js. The commit diff shows critical changes to the stack trace processing logic where host CallSite objects were not properly wrapped when passed through prepareStackTrace. The PoC demonstrates exploitation via frames.constructor.constructor() chain, which works because the frames array contained raw host CallSite objects. The patch adds proper wrapping through ensureThis() and sandboxSst handling, confirming this was the vulnerable path.
