Walkthrough

This pull request modifies the test implementation in packages/runtime-tags/src/__tests__/main.test.ts. The changes include removing the dependency on the ServerRenderer type and the ___id extraction from server-rendered templates. Fixture loading is updated to use fixtureDir instead of __dirname. The resume() flow is reworked to compile a separate CJS hydrate artifact from the template file and execute it via browser.window.Function with injected require binding, rather than calling init or initEmbedded directly. The changes also simplify the resume logic by eliminating embedded-specific branching and removing the preliminary template require call.
