Contributions summary:Injae primarily contributed to the Armeria framework by adding new functionalities related to query parameters and stream message operators. Their work involved modifying core Java files to include methods for handling query parameters within the `ServiceRequestContext`. Additionally, they implemented and extended `StreamMessage` operators such as `peek`, `peekData`, and `peekTrailers` to enhance the stream processing capabilities. These changes aimed to improve the framework's flexibility and facilitate easier debugging. Furthermore, the user addressed and fixed bugs within the `StreamMessage` conversion to `InputStream` to provide a more robust implementation.
