Skip unrelated required checks without losing their names (#2542)

* fix(ci): skip unrelated required checks cleanly

Matrix jobs had to start no-op runners to preserve interpolated required-check names. Static named jobs let GitHub report genuine skipped conclusions while keeping those names stable.

* fix(ci): gate changes to install patching script

* fix(ci): route cross-package test contracts narrowly

* fix(ci): keep routed contracts merge-blocking

* fix(server): exclude nested test utilities from builds

* fix(ci): cover app-owned native and browser domains

* refactor(ci): align tests with runtime domains

Own browser specs, desktop specs, and Electron-only app code by stable directories so PR routing does not depend on filename conventions. Keep desktop integration coverage inside the required desktop check.

* fix(ci): keep routing and desktop suites isolated

The routing regression must run before dependency installation, and desktop Vitest must not collect Playwright-owned specs.

* fix(ci): isolate desktop e2e runtime

* perf(test): isolate Playwright workers

* perf(test): parallelize Playwright within specs

* fix(test): keep Playwright file scheduling

* fix(test): share dynamic Metro fixture

* fix(test): preserve own-host restart fixtures

* fix(ci): preserve routed contracts after rebase

* Stabilize Playwright wheel-scroll assertions
