Neil 22a898e2d6 test(ssh): add E2E oracles for pane cardinality and duplicate resume
Both reported failures now have end-to-end coverage against a real Docker
OpenSSH relay, gated on ORCA_E2E_SSH_DOCKER like the rest of the suite.

- ssh-reconnect-pane-cardinality-across-partitions: three real reconnect cycles;
  after each, pane ids unchanged, exactly one live lease per leaf, exactly one
  remote shell per pane key, and exactly one pty id bound per leaf ACROSS BOTH
  durable partitions. Two partitions agreeing is tolerated; two naming different
  shells is the S4 divergence and fails. PASSES.
- ssh-reattach-does-not-resume-agent-twice: the host itself records one line per
  shell launch via a .bashrc hook keyed by ORCA_PANE_KEY, so a duplicate resume
  is counted at the source rather than inferred. Fault is SIGSTOP on the
  detached relay. PASSES.
- ssh-disconnected-pane-affordance: written whole but held as test.fixme. The
  banner needs the target CONNECTED while a single pane's attach fails, and both
  host-side faults drove the target out of connected instead. Held rather than
  deleted so it runs the day a seam exists; the reason is measured, not assumed.

New helpers: docker-ssh-relay-stall (SIGSTOP/SIGCONT, reads the stop back off
/proc so a fault that did not land cannot make an oracle vacuous), and
remote-pane-launch-transcript.

Note for whoever picks these up: a stalled relay leaves two detached relay groups
on the host, and readDockerSshRelayProcessSnapshot throws on more than one, so
call it before the fault.

Writing these is what surfaced RC2 surviving S3 — fixed in 7cd7fef927.
