Suggested test: copilot/doctor-command

## Motivation

Link to the gh-aw PR: github/gh-aw#45632 — feat: replace `setup auth`/`setup repo` with unified `doctor` command

The new `gh aw doctor` command consolidates hidden `setup auth` and `setup repo` into a single visible diagnostic. There is currently no E2E test that exercises this CLI path from within a workflow.

## Proposed test

- **Workflow file**: `test-copilot-doctor-command.md`
- **Trigger**: `workflow_dispatch`
- **Engine**: copilot
- **Safe output**: `create-issue`
- **Variant**: standard

## Minimal test prompt sketch

Run `gh aw doctor` in a pre-step and capture its output to a file. Have the agent read the output and create an issue reporting whether all diagnostics passed. This confirms the new command surface is callable from a compiled workflow and its output is parseable.

## New fixtures or secrets needed

None — `gh aw` is already available in the harness runner.

## Notes

The `test-copilot-gh-steps` workflow shows the pattern for capturing CLI output in `steps:` and passing it to the agent. No existing test covers the `doctor` command. Worth also checking whether the deprecated `setup auth` / `setup repo` aliases still work or have been removed entirely.

Start by reading test-copilot-gh-steps for the workflow pattern that captures CLI output in steps and passes it to the agent. Add test-copilot-doctor-command.md with workflow_dispatch, the copilot engine, a pre-step running gh aw doctor, and create-issue as the safe output. Done means the compiled workflow runs and the agent reports whether diagnostics passed; check whether the deprecated setup aliases still work.
