Adds an E2E test that deploys a VirtualMCPServer with 4 backends (yardstick, gofetch, osv, github) in a kind cluster, then validates: - Only find_tool and call_tool are exposed in optimizer mode - Cold-start FindTool request completes under 5 seconds - Search results are semantically relevant across all backends Addresses #3759 (200+ tools count to be added in a follow-up).

Summary
virtualmcp_optimizer_multibackend_test.go) that deploys a VirtualMCPServer with 4 backends (yardstick, gofetch, osv, github-mcp-server) and validates optimizer behavior: tool exposure, cold-start latency (<5s), and search quality across backends.GitHubMCPServerImageconstant for the github-mcp-server image used as a test backend.Addresses #3759
Type of change
Test plan
task lint-fix)Verified the new test file compiles cleanly with
go vet. The test is designed to run in a kind cluster withtask test-e2e(operator tests). CI will validate compilation and linting.Special notes for reviewers
The issue requests 200+ tools for scale testing. This PR uses 4 real MCP server backends which provide fewer tools. Scaling to 200+ tools is planned as a follow-up (likely by adding a tool-generation fixture or additional backends).
