[@grpc/grpc-reflection] lost dependency info

[hxzhao527]

Problem description

The current implementation of reflection lacks necessary information, causing debugging tools to not work properly.

reproduce steps

1. simple grpc-js server, e.g. https://github.com/parrotkesha/grpc-bug-yaak
2. use grpcurl to debug server

$grpcurl -plaintext localhost:8888 describe integration.JobService
Failed to resolve symbol "integration.JobService": proto: message field "integration.JobResponse.data" cannot resolve type: "*.google.protobuf.Struct" not found

Environment

• OS name, version and architecture: Linux archlinux 6.17.9-arch1-1 x86_64 GNU/Linux
• Node version : v25.2.1
• Node installation method : system package manager pacman
• If applicable, compiler version [e.g. clang 3.8.0-2ubuntu4]
• Package name and version

  "@grpc/grpc-js": "^1.14.3",
   "@grpc/proto-loader": "^0.8.0",
   "@grpc/reflection": "^1.0.4",
  

reason

Debugging tools need to obtain dependencies between FileDescriptorResponse through the reflection interface to resolve symbols.
