Auto suggestion not working on input, require manual trigger

Auto code suggestion should be run on typing.

- OS: Windows 11
- Visual Studio Code version: 1.101.2
- Amazon Q version: 1.79.0

Start by reproducing the issue in Visual Studio Code 1.101.2 with Amazon Q 1.79.0, comparing typing with the Alt+C manual trigger. Use the supplied telemetry to compare AutoTrigger and OnDemand behavior; done means suggestions appear while typing without requiring Alt+C and the existing telemetry still reports successful requests.
