Move the Messaging API back out of pkg/kernel: ffi.Handle becomes a defined type in the internal package, so kernel can hand the context to pkg/messaging through kernel.Handle without the kernel layer knowing the tier exists, and without the type being nameable outside this module. Split Discovery into DiscV5, PeerExchange and DNSDiscovery, group the node's identity and health under Debug(), and give every facade a pointer receiver. Drop the node name, the per-operation logging that duplicates what the library already writes, and GetFreePortIfNeeded — port 0 already means "let the OS pick". Heavy kernel tests now mark themselves with requiresNode and skip under -short, so the gate runs `go test -short ./...` instead of naming tests in a regexp.
