fix(hermes): one delivery path -- a VM takes its own messages on its own turn, never on another's stack

Browse Source

FABRIC-3.5 SXXXII, closing FABRIC-3 SXXIX bug 2 (SXXXVI).  A send marks the
receiver for the switch signal; the VM's own loop on its native stack takes
its messages and yields; Hera's idle beat makes the pending switch instead
of running other VMs' messages on her stack; every VM gets switcher turns
from birth; the drain refuses any call outside the VM's own context (the
test: it held every relayed line before, none now).

Found on the way: amd64's first-entry frame left rsp 8 bytes off the SysV
entry alignment (#GP on the first interpreter run on a VM's own stack), and
a VM yielding from its loop was marked SWITCHED_OUT, which stopped console
relay after one message and would have made KILL refuse it.

Relay of four lines to a WIREBIND identity on all three ISAs, five
hot-plugged identities, and standard acceptance (POST 1052, hash
0x08873e0f44b7cb2a) all pass.
