Suggested test: copilot/inline-engine-driver

## Motivation

Link to the gh-aw PR: github/gh-aw#47991 — Add inline `engine.driver` sources for Copilot SDK workflows. The compiler now materializes inline Node, Python, Go, or Java driver sources at runtime from frontmatter, eliminating the need to commit a separate driver file.

## Proposed test

- **Workflow file**: `test-copilot-inline-engine-driver.md`
- **Trigger**: `workflow_dispatch`
- **Engine**: copilot (SDK mode with inline driver)
- **Safe output**: `create-issue`
- **Variant**: standard

## Minimal test prompt sketch

The workflow frontmatter declares a short inline TypeScript (Node) driver under `engine.driver.inline`. The driver calls the Copilot SDK to produce a `create-issue` safe output with a known title. The test verifies the issue is created, confirming that inline driver materialization and execution works end-to-end.

## New fixtures or secrets needed

None. An inline Node/TypeScript driver is self-contained and compiled at runtime by `gh aw compile`.

## Notes

No existing test exercises the inline `engine.driver` path — all current `copilot-*` tests use the default engine configuration. This is a net-new compiler feature deserving its own regression test. Should eventually be extended to Python and Go drivers, but one variant (Node/TypeScript) is sufficient for a first test.

Create test-copilot-inline-engine-driver.md with a workflow_dispatch trigger and the inline Node/TypeScript driver described in the issue. Start by reading the existing copilot-* tests and the gh aw compile entry point; run the new workflow and confirm it produces the expected create-issue safe output without additional fixtures or secrets.
