This PR has been marked as AI slop and the description has been updated to avoid confusion or misleading reviewers.

Many AI PRs are fine, but sometimes they submit a PR too early, fail to test if the problem is real, fail to reproduce the problem, or fail to test that the problem is fixed. If you think this PR is not AI slop, please leave a comment.

Fixes issue #15310 where CSS imports with type attributes were being
stripped during transpilation.

- Preserve 'with { type: "css" }' and 'with { type: "json" }' in
  transpiler output as these are web standard import attributes
- Keep Bun-specific attributes (toml, sqlite, etc.) only when
  is_bun_platform is true to maintain compatibility
- Add comprehensive regression tests

This ensures compatibility with the standard CSS modules proposal
while maintaining Bun's extended import capabilities.

…ests

- Moved tests to separate file to avoid interfering with existing import-attributes tests
- Tests specifically target transpiler behavior for issue #15310
- All tests pass and verify the fix works correctly
- Add 'webassembly' mapping to wasm loader in options.zig
- Update transpiler to preserve all web standard import attributes:
  - CSS (type: 'css')
  - JSON (type: 'json')
  - WebAssembly (type: 'webassembly')
- Add comprehensive tests for WebAssembly import attributes
- Ensure Bun-specific attributes are still handled correctly

This completes the fix for issue #15310 by supporting all three
major web standard import attribute types while maintaining
backward compatibility with Bun's extended capabilities.
