* Update @github/copilot to 1.0.67

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

* Fix hook tests for Copilot 1.0.67

Adapt hook E2E coverage to assert SDK callbacks are invoked now that the runtime accepts hook handlers. Include missing client-global RPC types generated from the updated schema.

* Update generated Go RPC comments

Include experimental annotations emitted by the Go code generator for newly generated RPC types so generated-file verification stays clean.
