We decided to implement a new approach without the need of creating a .port file.

🚀 Summary
The manual test server (createserver.js) now automatically finds a free port at startup. When the preferred port (default 8125) is already in use, it tries subsequent ports via recursive
tryListenOnPortuntil a free one is found, withserver.close()on each failed attempt to release the handle. The--portCLI option sets the starting port. Tests cover port retry onEADDRINUSE, rejection on other errors, and all existing behavior updated to use asyncserver.listenwith callbacks.📌 Related issues
💡 Additional information
Testing: Block the port 8125 with any server, then launch manual tests. They should start at 8126.
