This adds a guarded upstream MCP proxy backend for streamable-HTTP servers. The proxy snapshots an allowlisted upstream tool surface, preserves the upstream tool schema where possible, and fails closed on unknown tools or schema drift.

  • Added serve-upstream for the proxy backend
  • Added tests for allowlisted projection, call forwarding, and schema-drift rejection
  • Verified with go build ./..., go vet ./..., and go test ./...

closes #18
