fix: verify native prebuild fixtures

[wanxiankai]

Summary

• parse each Apple framework Info.plist and verify its executable and bundle identifier
• add the competing .node fixture to the Babel plugin test
• preserve Node.js module resolution precedence when JavaScript and native addon files share a basename

Test plan

• pnpm run build
• pnpm --filter react-native-node-api test (61 tests passed)
• pnpm exec eslint packages/host/src/node/babel-plugin/plugin.ts packages/host/src/node/babel-plugin/plugin.test.ts packages/node-addon-examples/scripts/verify-prebuilds.mts
• pnpm run prettier:check

Closes #424

Sorry, this needs a rebase now 🙈

[wanxiankai]

Rebased onto the latest next and force-pushed as 2d4f74f. I also switched the plist parser to the package-level @expo/plist export. The branch is now conflict-free.

Re-ran:

• pnpm run build
• pnpm --filter react-native-node-api test (61/61 passed)
• targeted ESLint
• pnpm run prettier:check

Everything passes locally. The GitHub Actions workflow is currently awaiting maintainer approval.
