* Replace compile-time directives with target platform conditions
Use Package.swift target platform conditions instead of compile-time #if directives for EventSource dependency. This leverages Swift Package Manager's native dependency support for platform-specific targets at runtime rather than compile-time.
* Update reference for EventSource package

* Delay SSE GET connection until after session ID is established
- Add a signaling mechanism to ensure the SSE streaming task waits for the initial session ID to be set before attempting the GET connection.
- Use a TaskGroup to race between session ID signal and a 10-second timeout, logging the outcome.
- Trigger the signal when a session ID is received for the first time from any response.
- Add detailed logging for all code paths to aid debugging and clarify connection timing.
- Clean up signal resources on disconnect to prevent leaks.
This addresses the initialization timing issue where the SSE GET could be attempted before the session was established, as discussed in MCP PR #91.
