Add a "Superseded (2026-07-11)" banner and flip Status: Active →
Superseded on the 8 smolmachines-specific docs (7 PRDs + the VM-backend
research). Bodies are left intact as a historical record; the banner
points at the removal commit and the landscape doc so a reader isn't
misled into thinking the backend still exists.
Incidental mentions in other PRDs (git-gate, cred-proxy, print-parity,
etc.) are left as-is.

Compares smolmachines against the six subsystems in
agent-vm-isolation.md. smolmachines replaces the microVM runtime,
network attachment (libkrun TSI with built-in DNS-over-vsock filter),
vsock control plane, and Python lifecycle wrapper. Pipelock stays;
disk-image story shifts to OCI + writable overlay. Recommends adopting
smolmachines as the macOS VM backend after smoke-testing TSI
passthrough to a host-side pipelock.
