The package declares @angular/* >=20 and Node >=22, but CI only ran on the repository's Angular 22 and Node 24. Add a compatibility workflow that runs the page-side tests against Angular 20.0, 21 and 22 on Node 22, on pushes to main, weekly and on demand. The job overrides the Angular versions at install time, and vitest.compat.config.ts picks the tests that render a real app. Tests for features from later releases check the Angular version and skip. The first run on 20.0 found two collector gaps, fixed here: navigation extras were missing because currentNavigation is a plain field before 20.2, and the forRoot scroller showed as off because its token has no description on 20.0. List the tested versions on the Installation page. Closes pangular-inspector#100

📝 WalkthroughWalkthroughThe pull request adds Angular-version compatibility tests, adjusts router handling for Angular API variations, and adds a workflow that runs page-side tests across Angular 20, 21, and 22. It also updates setup action inputs and documents tested versions. ChangesAngular Compatibility

Merge Risk: 🔵 Low · up to Angular 20/21 compatibility failures may reach main before the matrix detects them. Running the matrix on pull requests would catch those regressions before merge. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The compatibility jobs use read-only repository permissions and do not publish or deploy anything. The router changes preserve existing navigation ownership and avoid collecting raw navigation-state values. No material security regression was identified in the inspected paths, but incomplete coverage limits confidence. Retained concerns Security review detailsSecurity Blast Radius

- Around line 113-114: Update the imports and factory references in the router
setup test so withExperimentalAutoCleanupInjectors and
withExperimentalPlatformNavigation are resolved through an import-safe namespace
lookup with optional property access, avoiding static named imports that fail on
Angular versions without those exports. Keep the ɵwithRouterResources binding
separate from the public withRouterResources import.

Named imports of withExperimentalAutoCleanupInjectors, withExperimentalPlatformNavigation and ɵwithRouterResources fail to link under native ESM on Angular versions that lack them, so read them from the module namespace instead.

.github/workflows/compat.ymlruns only on pushes tomain, on a schedule, or manually. The pre-merge CI runs the defaultpnpm test:devtoolscommand without the compatibility configuration or Angular 20/21 dependency overrides. It may cover overlapping tests for one Angular version, but an Angular 20 or 21 regression can reachmainbefore this matrix detects it.Suggested fix
