AUI-51 / Feat: Upgrade to Angular 21, Vitest, standalone, oxfmt (#1420)

* feat!: update packages to 21, make standalone, switch from jest to vite

- Upgrade all @angular/* packages from v20 to v21
- Replace @angular-builders/jest with @angular/build:unit-test (Vitest runner)
- Upgrade RxJS from v6 to v7, add npm overrides for @hypertrace/hyperdash peer dep
- Make all library and app components/directives/pipes standalone
- Remove deprecated APIs: ComponentFactoryResolver, HttpClientTestingModule, *ngIf/*ngFor
- Replace zone-dependent test utilities (fakeAsync/tick) with Vitest fake timers
- Remove @ngneat/spectator, zone.js, and all Jest-related dependencies

BREAKING CHANGE: Update Angular to v21, RxJS to v7,
make components standalone, switch from Jest to Vitest

* chore: change from prettier to oxfmt

* fix: fix broken test under node 20

* docs: update README for Vitest and fix commit command

* chore: remove check overrides

* test: replace istanbul comments with v8 comments

* test: make test components standalone

* fix: restore RxJS 6 compatibility for Angular 21

Revert the branch to RxJS 6 and align published peer
constraints with upstream hyperdash requirements.
Add a shared Vitest runner config so Angular 21 tests
resolve correctly when RxJS 6 is installed.

* chore: remove redundant standalone directive

* chore: remove redundant standlone metadata

* chore: remove Codecov

* chore: clean up stale tooling artifacts and review findings

- Remove eslint-config-prettier and its ESLint extends entry (replaced by oxfmt)
- Remove ts-node devDependency (no longer needed after Jest→Vitest)
- Remove stale .vscode/launch.json (referenced deleted Jest config)
- Remove emitDecoratorMetadata from tsconfig (unnecessary for Angular)
- Remove duplicate deserialization-manager.service export in public_api
- Remove vestigial standalone param from mockDirective test utility
- Widen rxjs peer dependency to ^6.5.5 || ^7.0.0
- Enable @angular-eslint/prefer-standalone lint rule
- Add non-standalone renderer backward compatibility test
- Add util/ to coverage exclusions (types-only files)
- Update README with Angular 21 prerequisites and RxJS 6+7 support

* fix: filter pre-commit hook to formattable file types

* chore: change to node 22

* chore: migrate from npm to pnpm

Replace npm with pnpm as the package manager across the repo:
- Add packageManager field and pnpm config to package.json
- Add ci script for frozen-lockfile installs
- Update CI workflows to use pnpm with node_modules caching
- Align publish workflow to Node 22
- Replace package-lock.json with pnpm-lock.yaml
- Update CLAUDE.md command references

* fix: approve lmdb and msgpackr-extract build scripts for pnpm

These native addons are transitive dependencies of @parcel/watcher
used by the Angular build toolchain. Without their build scripts
running, native bindings aren't compiled, causing AOT compilation
issues in CI.

fix: Upgrade to angular v20 (#1415)

* fix: update Angular to v20
* chore: add CLAUDE.md file
* chore: remove unneeded deps
* chore: update husky
* fix: restore dashboard configuration for standalone bootstrap
