Update @github/copilot to 1.0.39 (#1167)

* Update @github/copilot to 1.0.39

- Updated nodejs and test harness dependencies
- Re-ran code generators
- Formatted generated code

* Fix flaky multi-client reject permission test

Mirror the synchronization pattern from the 'approve' sibling: capture a
PermissionCompletedEvent task on session2 before subscribing and sending,
then await it before asserting that client2 observed PermissionRequestedEvent.
Without this wait, client2's event subscription could be asserted before the
event had propagated, causing intermittent failures (observed on macOS CI).
