feat(rstest): add preserveNewUrl option to keep new URL untouched

[fi3ework]

Summary

• Add preserveNewUrl option to RstestPlugin (default: false)

• When enabled, matched new URL expression like new URL("*.wasm", import.meta.url) expressions are preserved in output, this is useful in testing case, especially for following code:

  const path = new URL('a.wasm')
  const binary = fs.readFile(path)

• Non-matched assets continue to be processed normally

Summary of Changes

Hello @fi3ework, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the RstestPlugin by introducing a preserveNewUrl option. This feature provides finer control over how new URL() expressions are handled, specifically allowing WebAssembly module URLs to remain un-transformed in the output. This is crucial for scenarios where the original URL structure for WASM assets is required, while ensuring that other asset types continue to benefit from RstestPlugin's standard processing.

Highlights

• New Option preserveNewUrl: Introduced a new preserveNewUrl option to the RstestPlugin configuration, which defaults to false.
• WASM URL Preservation: When preserveNewUrl is enabled, new URL("*.wasm", import.meta.url) expressions are no longer processed by RstestPlugin, ensuring they remain untouched in the output bundle.
• Normal Asset Processing: Non-WASM assets (e.g., .png) referenced via new URL() continue to be processed normally by the RstestPlugin, even when preserveNewUrl is active.
• Test Coverage: Added new test cases to validate the behavior of the preserveNewUrl option for both WASM and non-WASM assets, ensuring correct functionality.

Pull request overview

This PR adds a preserveNewUrl option to the RstestPlugin to keep new URL("*.wasm", import.meta.url) expressions untouched in the output, which is useful for testing scenarios where the original URL construction needs to be preserved (e.g., when using fs.readFile() with WASM paths in tests).

Key Changes:

• Added preserveNewUrl boolean option (default: false) to RstestPlugin configuration
• Implemented custom URL dependency template that skips transformation for .wasm files when the option is enabled
• Non-wasm assets continue to be processed normally through the standard URL dependency template

Code Review

This pull request introduces a preserveNewUrl option to the RstestPlugin to prevent new URL("*.wasm", ...) expressions from being processed, which is useful in testing environments. The implementation is clean, adding a new dependency template to conditionally handle URL dependencies, and is well-supported by new tests. My feedback includes a minor cleanup to remove an unused import.
