The uuid package dropped its CommonJS entry point in v14, making it
incompatible with Backstage's CJS build output and Jest test runner.
Rather than working around the ESM-only issue, replace all usage with
the built-in crypto.randomUUID() which has been available in Node.js
since v16.7 and in all major browsers since March 2022.

* fix: avoid destructuring FetchApi and fix template issues
- Use fetchApi.fetch() instead of destructuring to preserve this binding
- Add discoveryApi and fetchApi to useAsync dependency array
- Use react-use/esm/useAsync to match repo conventions
- Replace waitFor + getAllByText with findByText in error test
- Update HTTP client doc to match template changes

* fix: improve error handling in e2e plugin creation
- Narrow error to non-null object before using in operator
- Also write error.stdout since tools like Jest report to stdout
- Avoid variable shadowing with outer scope stdout/stderr

* revert: keep destructured fetch from FetchApi
Destructuring fetch from FetchApi is fine — revert to original
pattern while keeping the dependency array and other fixes.

* feat: use @backstage/ui components in frontend plugin template
Replace core-components layout and table with @backstage/ui equivalents:
- Use HeaderPage and Container instead of Page, Header, Content, ContentHeader
- Use BUI Table with useTable and CellText instead of core-components Table
- Add @backstage/ui to template package.json dependencies
- Update poking-around docs to reflect BUI component usage

Add a `toError` utility function to `@backstage/errors` that converts
unknown values to `ErrorLike` objects. If the value is already error-like
it is returned as-is. Strings are used directly as the error message, and
other values are stringified with a fallback to JSON.stringify to avoid
unhelpful `[object Object]` messages.
Non-error causes passed to `CustomErrorBase` are now converted and stored
using `toError` rather than discarded. Existing `assertError` call sites
across the codebase are migrated to `toError`.

The legacy frontend plugin template had the same name (`frontend-plugin`) as
the new frontend plugin template, causing a conflict error when both were shown
(e.g. when the frontend system could not be auto-detected). Rename the legacy
template to `frontend-plugin-legacy` so both can coexist.

The known plugin package ID mappings don't need to be part of the
public API surface. Move them to @internal/cli and update consumers.

Renamed the CLI templates for frontend plugins:
- new-frontend-plugin → frontend-plugin
- new-frontend-plugin-module → frontend-plugin-module
- frontend-plugin (legacy) → legacy-frontend-plugin
Added auto-detection logic that checks packages/app/package.json to
determine which frontend system the app uses. When using default
templates, only the appropriate frontend plugin template is shown:
- Apps with @backstage/frontend-defaults see the new system templates
- Apps with @backstage/app-defaults see the legacy template
Both templates display as "frontend-plugin" to users, so existing
workflows are preserved while automatically using the correct template.

The templates directory was excluded from linting in the @backstage/cli
package but the ignore pattern was not carried over to cli-module-new.

The built-in templates used by `yarn new` are moved from `packages/cli/templates/`
to `packages/cli-module-new/templates/`, colocating them with the code that
consumes them.
A backwards compatibility rewrite in the template resolution ensures that
existing `@backstage/cli/templates/*` references in root `package.json`
configurations continue to work by transparently resolving them to
`@backstage/cli-module-new/templates/*`.

Add a new `cli-module` template to the Backstage CLI that scaffolds
CLI module packages. This includes adding the `cli-module` role to the
template system, with proper naming conventions and prompts.
The generated package includes:
- A bin entry point for standalone execution
- An index.ts with createCliModule setup
- An example command using cleye
- Standard package.json with cli-module role
