Only suspend the lazy BUI CSS import so the app root keeps its built-in loading UI, and lock that behavior down in the mocked render test.

Align the dev app render path with the existing dev-utils helper, add a clearer missing-root error, and extend the tests to cover bindRoutes forwarding and env cleanup.

Define createDevApp options directly so the helper only exposes features and a typed bindRoutes property without inheriting from createApp options.

Limit createDevApp to features and bindRoutes so advanced createApp configuration stays out of the dev-app helper API.

Accept createApp options at the top level in createDevApp and update the tests, docs, API report, and changeset to match the new shape.

Adds a new `@backstage/frontend-dev-utils` package for the new frontend
system. It provides a minimal `createDevApp` helper for wiring up a
development app from a `dev/` entry point.
The app-visualizer plugin is updated to use this new package as the
initial testing ground.
