Closes §I.3 (Milestone 5 remainder): WIREBIND now tracks which VM is
attached via the home-blocks USB path, and a new EJECT word plus the
existing hot-unplug signal both flush/reset-console/kill through it
(FABRIC-3.md §F.10).
Closes §I.8 (EXPIRE/ACL), re-scoped: the original "admit the zuse
session as a Stadium patron and reap on TTL" plan was invalidated a
second time -- Zuse authenticates directly onto Hera, who is patron
zero and permanently pinned, so there is no patron for a reap sweep to
ever find. Built instead as a detach-triggered logout
(capsule_zuse_boot_logout()), the same trigger EJECT/hot-unplug use for
regular WIREBIND users, so neither identity is a special case. Required
a companion fix: install_and_activate() used to skip re-running
ACL-ZUSE-BOOT whenever the cert was already installed, which made a
logout permanent for the rest of the boot; the outer re-attach gate now
checks zuse_session (clears on logout) instead of zuse_cert_installed
(a deliberate permanent one-way ratchet, left untouched).
Verified 3-arch boot to ok> (amd64/aarch64/riscv64, each in the
foreground) after both steps; logs and DoE CSVs from this session's
verification runs included per this repo's own audit-artifact
convention.
