unikernels: restore native cram coverage Opt local network fixtures into loopback egress now that the native slirp backend preserves the default SSRF denylist. Refresh the TCP compute probes and tm-downlink table transcript to match their current programs.

unikernels: turn tcp-server and tcp-client into a multicore probe The echo pair proved the stack; it could not show whether the domains pool buys anything over TCP. The server now offloads a CPU-bound LCG chain per connection to the pool (accept and socket I/O stay on the boot domain, where the from-scratch stack lives), and the client fires the same requests sequentially then all at once: the ratio is the multicore speedup as seen from outside, checksum-verified both ways.

tcp-client unikernel demo

A TCP client over the guest's Ethernet, ARP, IPv4, and TCP stack. It connects to an echo service, writes one line, and prints the echoed response.

The example is the smallest end-to-end use of a stream flow. It shows the connection lifecycle and the point where a protocol client can be layered over Eio.Flow.
