Contributions summary:Evgenii primarily contributed to the `swarm` library by fixing and improving the test cases related to the `BatServer`, `syncable` and `OpStream`. They addressed issues where messages were concatenated and updated test cases to account for the handshake process. Moreover, the user refactored `OpStream` to convert it into a Duplex stream, implementing `_read()` and `_write()` methods. The user also updated the project's dependencies, specifically the `gw` module to use the 1.0 API.
