fix: remove unused CJS require of ESM-only @storybook/test-runner

[Copilot]

@storybook/test-runner@0.24.2 ships as ESM-only ("type": "module"). .storybook/test-runner.cjs was require()-ing it, failing all 78 Storybook test suites on main:

Must use import to load ES Module: .../node_modules/@storybook/test-runner/dist/index.js

• Removed require('@storybook/test-runner') — getStoryContext was imported but never referenced
• Removed require('jest-snapshot') — toMatchSnapshot was imported but unused (expect().toMatchSnapshot() uses Jest's built-in matcher)

No functional change to prepare, preVisit, or postVisit hooks.

Pull request overview

This PR fixes a critical ESM/CJS compatibility issue that was causing all 78 Storybook test suites to fail. The @storybook/test-runner@0.24.2 package is ESM-only, but .storybook/test-runner.cjs was attempting to require() it, resulting in "Must use import to load ES Module" errors.

Changes:

• Removed unused require('@storybook/test-runner') that imported getStoryContext (never referenced in the code)
• Removed unnecessary require('jest-snapshot') that imported toMatchSnapshot (Jest matcher is globally available in test-runner environment, no explicit import needed)
