Ensure resource-collection gzip payloads include the footer

Description

The generated resource-collection.js.gz payload was read before GZipStream disposal completed, so the gzip footer was omitted and some clients/tools rejected the response as truncated.

• Runtime fix

  • Update CreateGzipBytes to dispose GZipStream before reading the underlying MemoryStream.
  • This ensures the final gzip trailer is written before the endpoint caches and serves the compressed bytes.

• Coverage

  • Add a focused endpoint test that exercises the generated .js.gz route.
  • Verify the response decompresses successfully and matches the uncompressed resource-collection.js payload.

private static byte[] CreateGzipBytes(byte[] bytes)
{
    using var gzipContent = new MemoryStream();
    using (var gzipStream = new GZipStream(gzipContent, CompressionLevel.Optimal, leaveOpen: true))
    {
        gzipStream.Write(bytes);
    }

    return gzipContent.ToArray();
}

Pull request overview

Fixes generation of resource-collection.js.gz so the gzip trailer/footer is included before the payload is cached and served, preventing clients/tools from treating the response as truncated.

Changes:

• Dispose GZipStream before reading from the underlying MemoryStream to ensure the gzip footer is written.
• Add an endpoint-focused test that requests the .js.gz endpoint, decompresses it, and verifies it matches the uncompressed .js endpoint output.

File	Description
src/Components/Endpoints/src/Builder/ResourceCollectionUrlEndpoint.cs	Ensures gzip bytes are materialized only after GZipStream disposal so the trailer is present.
src/Components/Endpoints/test/Builder/ResourceCollectionUrlEndpointTest.cs	Adds coverage validating the .js.gz response fully decompresses and matches the uncompressed payload.
