Add explicit scope metadata to Pi permission events. server/drivers/pi.ts omits cwd and workspaceBound, so eligible Pi permission requests cannot pass unscoped-guard and cannot run unattended. Set cwd to the request’s working directory and set workspaceBound to the actual provider guarantee.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the unattended decision field.

This test verifies the approval source but not the unattended provenance named in the test. A regression that omits unattended: true would still pass.

Proposed fix 
       expect(row, "the webhook auto-approval never reached the decision log").not.toBeNull();
       expect(row!.source).toBe("always-allow");
+      expect(row!.unattended).toBe(true);
