Subject: [PATCH] Fix router disabled provider check + comprehensive functional
 tests

Fixes:
- Router now properly skips disabled providers in complete() method
- Fixed avg_latency calculation comment in tests (now correctly documents behavior)

New Test Suites:
- tests/test_functional_router.py: 10 functional tests for router
- tests/test_functional_mcp.py: 15 functional tests for MCP discovery/bootstrap
- tests/test_integration_full.py: 14 end-to-end integration tests

Total: 39 new functional/integration tests

All 144 tests passing (105 router/mcp + 39 functional/integration)
