🐞 Bug Summary

The mcpgateway.federation module (containing DiscoveryService and ForwardingService) is currently unused and not wired into the application lifecycle.

• DiscoveryService (mDNS auto-discovery) is not required for the current deployment model.
• ForwardingService logic is largely duplicated by ToolService, which implements a more advanced version of tool invocation (supporting OAuth, Plugins, SSE).

To reduce technical debt and confusion, this unused code should be removed.

Note: Check all the corresponding dependencies, documentation, env variables and more related to federation for cleanup

🧩 Affected Component

Select the area of the project impacted:

• mcpgateway - API
• mcpgateway - UI (admin panel)
• mcpgateway.wrapper - stdio wrapper
• Federation or Transports
• CLI, Makefiles, or shell scripts
• Container setup (Docker/Podman/Compose)
• Other (explain below)

🔁 Steps to Reproduce

1. Inspect mcpgateway/main.py and observe that DiscoveryService and ForwardingService are never instantiated.
2. Inspect mcpgateway/services/tool_service.py (invoke_tool method) and verify it manages its own connections to remote gateways, bypassing ForwardingService.
3. Check mcpgateway/federation/ directory to see the dead code.

🤔 Expected Behavior

The codebase should be clean and devoid of large blocks of unused or duplicate code. The mcpgateway.federation package should be deleted.
