Research direction

The issue requests support for multiple simultaneous PHP debugging sessions in vdebug. The first step is to study the current implementation of debugger connection handling in the main Python files (e.g., vdebug.py or debugger.py). Understand how a single DBGP session is initiated and managed. Then, review the linked PhpStorm documentation for simultaneous sessions to identify required protocol changes. The fix likely involves modifying session management to allow multiple concurrent connections, possibly using unique session IDs. Proposed changes should be discussed in the issue before implementation.
