The supervisor mounted the forge on the happy path but could not
re-attempt: mount() returned silently on inject/handshake failure, and a
live-but-uninjected binding never died to trigger a rebind, stranding the
forge for the life of that soterserver process (audit F1).
Route every unmounted outcome through scheduleRetry(): inject failure,
post-inject handshake-null, and register failure now schedule a re-bind
instead of returning. Add onNullBinding (F2) and exponential backoff
capped at 30s, reset on a clean mount (F3). register() now returns
whether the transact succeeded so mount() retries on a false reply (F4);
existing keystore callers ignore the new return.
Audit remediation. compileDebugKotlin clean.
