Allow plugin and extension overrides to replace or remove existing if predicates. This makes conditional plugin and extension behavior overrideable through both plugin overrides and module-installed extension overrides.

This documents the new phased app preparation flow and conditional feature behavior in the frontend-system docs, and adds the missing changeset coverage for related published package changes.

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

across three docs pages: the frontend system building plugins guide,
the CLI build system reference, and the project structure overview.

Rename "package discovery" to "feature discovery" across all plugin
READMEs and docs to match the established terminology. Slim down the
Feature Discovery section in the architecture docs to avoid duplicating
the configuration details now covered in the installing plugins page.

Update the Building Apps overview to reference the new installing
plugins page instead of duplicating feature discovery content. Add
cross-references between the installing plugins page, the architecture
feature discovery docs, the plugin conversion page, and the extension
configuration page.

Restructure plugin documentation so that the new frontend system is
the default, unlabeled installation path. Old frontend system
instructions are moved to a dedicated "Old Frontend System" section.
Add a new "Installing Plugins" page to the frontend system docs
covering package discovery, manual installation, and configuration.

This adds a test utility that simplifies testing entity cards and content
extensions in the new frontend system. The utility creates a test page
that provides EntityProvider context and accepts entity extensions through
input redirects.
Also adds the `apis` option to `renderTestApp` for API overrides, and
includes tests for entity cards in catalog, org, and api-docs plugins.

Adds the snapshot() method to ExtensionTester, enabling snapshot
testing of extension tree structures. The snapshots use a tree-shaped
format that mirrors the extension hierarchy, with empty fields and
default values omitted for clarity.

Added support for API overrides in `createExtensionTester` and
`renderInTestApp` to allow tests to override specific APIs without
requiring wrapper components. This provides app-level API overrides
that are available throughout the entire extension tree.
The `apis` option follows the same typing pattern as `TestApiProvider`
from `@backstage/test-utils` for consistency and type safety.
Example usage:
```typescript
const tester = createExtensionTester(MyExtension, {
apis: [
[errorApiRef, mockErrorApi],
[analyticsApiRef, mockAnalyticsApi],
],
});
renderInTestApp(<MyComponent />, {
apis: [
[errorApiRef, mockErrorApi],
[analyticsApiRef, mockAnalyticsApi],
],
});
```
This enables cleaner tests with app-level API overrides, eliminating
the need to wrap components with TestApiProvider in many cases.
