chore: migrate Rstest to Rstack CLI

[chenjiahan]

Summary

This PR migrates the monorepo's Rstest commands and configurations to Rstack CLI while preserving the existing unit and E2E behavior. It replaces direct @rstest/core imports and type entries with rstack/test, removes the direct core dependency outside the create-rsbuild templates, and keeps the explicit Rslib adapter and Playwright integrations. The temporary Playwright hook type workaround links to the upstream fix and can be removed after it is released.

📝 Walkthrough

Walkthrough

The test setup was migrated from direct rstest usage to rstack test. Root and E2E configurations now use define.test, package scripts invoke rs test, and obsolete @rstest/core dependency entries were removed. Test TypeScript configurations now use rstack/test/globals, setup imports use rstack/test, and E2E fixture typings define custom rstack-compatible test signatures.
