Add CLI E2E coverage for WithTerminal attach flow

[mitchdenny]

Description

Adds a CLI end-to-end test that exercises WithTerminal for the TypeScript Express/React starter flow.

The test now validates the full terminal scenario users rely on:

1. scaffold the Express/React starter,
2. update apphost.mts so frontend uses .withTerminal(),
3. start the app host and wait for terminal availability via aspire terminal ps (text output),
4. run aspire terminal attach frontend,
5. trigger Vite help with h + Enter and assert the help menu appears,
6. detach with Ctrl+B then D, then stop the app host.

This adds coverage for the interactive attach/detach workflow and terminal availability checks from the CLI perspective.

Pull request overview

This PR adds a new CLI end-to-end test that validates the interactive WithTerminal attach/detach workflow for the TypeScript Express/React starter template. It exercises the full terminal lifecycle from the CLI perspective.

Changes:

• Adds TerminalCommandTests.cs with a single test that scaffolds a TypeScript Express/React project, modifies apphost.mts to add .withTerminal() on the frontend resource, waits for terminal availability via aspire terminal ps, attaches to the frontend terminal, triggers Vite help, and detaches cleanly.
