Scope VM fault halt to the faulting identity's own session (FABRIC-3.md §XI.4)

A standalone WIREBIND identity (no Zuse, USE'd in directly) hitting an
ACL-denied word halted the entire machine -- Hera, Hermes, Artemis, all
of it -- instead of just that identity's own session. sk_fault_handler()
was being called unconditionally on whichever VM's ->error was set, with
no distinction between Hera's own root session (where "no fallthrough
surface" is the correct, deliberate fail-closed behavior) and a
USE'd-in guest identity (which should recover and resume at its own
prompt instead of taking the fleet down with it).

Both call sites (sk_repl_step, sk_repl_run) now compare the faulting VM
against Hera before deciding: Hera's own session still halts by design;
any other VM prints a recovery message, clears its fault state, and
continues.

Also: mint identities 01-06 with the same FORTH-79/83 restricted
personality identity 00 already had, verified via the fixed fault
scoping above (which this verification pass surfaced).

Verified live on amd64 (both the Hera-halts and identity-recovers
branches); three-arch clean qemu acceptance passed (riscv64's first
attempt hit an unrelated virtio_blk I/O timeout hang, a known QEMU/TCG
flake -- a clean retry booted normally).
