Est. 0 Premium requests

### Describe the bug

I love the Copilot CLI and `autopilot` and `/fleet` ( see [HERE](https://dev.to/kryvoff/meet-coco-the-copilot-for-copilot-42ko) or [HERE](https://github.com/wesm/agentsview/issues/23) ). Thank you!

It looks like there's a bug where it claims very long sessions with 10-20 million tokens used up est. 0 premium requests.

This is what I got just now after a session with GPT Codex:
```
% copilot --yolo
Total usage est: 0 Premium requests
API time spent: 41m 22s
Total session time: 47m 28s
Total code changes: +8 -2
Breakdown by AI model:
gpt-5.3-codex 18.9m in, 92.4k out, 16.9m cached (Est. 0 Premium requests)
claude-haiku-4.5 321.7k in, 3.3k out, 290.1k cached (Est. 0 Premium requests)
```

And the same with Claude Opus:
```
% copilot --yolo
Total usage est: 0 Premium requests
API time spent: 29m 56s
Total session time: 37m 48s
Total code changes: +647 -45
Breakdown by AI model:
claude-opus-4.6 14.2m in, 67.2k out, 13.9m cached (Est. 0 Premium requests)
claude-haiku-4.5 2.0m in, 22.1k out, 1.8m cached (Est. 0 Premium requests)
```

Can you please try to fix the premium request estimate (ideally count and don't estimate)?

Also would be nice to have a bit more info about the session like e.g. how many subagents or turns or tool calls.

### Affected version

GitHub Copilot CLI 0.0.420.

### Steps to reproduce the behavior

Select yolo, autopilot and `/fleet` and submit any prompt.

### Expected behavior

Copilot shows premium request count or at least an estimate > 0.

### Additional context

MacOS, VS Code terminal.
