feat(angular): angular adapter and utils (#368)

* feat(angular-devtools): create angular adapter package

Add the @tanstack/angular-devtools package with:
- TanStackDevtoolsComponent: standalone Angular component that wraps TanStackDevtoolsCore
- Plugin system supporting Angular components rendered into devtools containers
- Type definitions for Angular-specific plugin and init configuration
- Build config using @analogjs/vite-plugin-angular for AOT compilation

* fix(angular-devtools): add reactivity for input changes, remove unused RenderArray

* feat(devtools-utils): add angular support

* fix: resolve angular build issues

- Remove @analogjs/vite-plugin-angular from build (produces empty chunks
  for library builds). Use plain esbuild via Vite instead - Angular AOT
  compilation happens at consumer's build time.
- Upgrade Angular dev deps from ^19 to ^20 for TypeScript 5.9 compat.
- Remove @angular/build dep (only needed by analogjs plugin).
- Add @tanstack/angular-devtools workspace override to root.

* ci: apply automated fixes

* fix: resolve lint, knip, and sherif issues

- Fix array-type ESLint rule in angular-devtools
- Fix import/consistent-type-specifier-style in devtools-utils angular
- Sort peerDependencies alphabetically (sherif)
- Remove unused devDependencies flagged by knip
- Remove angularCompilerOptions from tsconfig (not using ngc)

* feat: add Angular support with setup, adapter, and custom plugin documentation

* feat(angular): angular adapter add utils and some examples, fix build

* ci: apply automated fixes

* feat: Add angular adapter and devtools-utils/angular

* remove afterNextRender in devtools-utils

Since angular-devtools already run the code within afterNextRender in browser env, we don't like to wrap the panel returned from utils

* fix examples

* fix angular devtools wrong pnpm link

* feat(angular-devtools): add with-devtools provider

* docs(angular-devtools): update docs

* ci: apply automated fixes

* chore(angular-devtools): fix examples dependencies and knip issues

* feat(angular-devtools): rename withDevtools to provideTanStackDevtools

* Add a11y plugin for angular

* chore(deps): update @tanstack/devtools and related packages

* ci: apply automated fixes
