* fix(ssh): stop pane adoption certifying a death from the relay's not-found union
`attachStablePaneOwner` was the last reader that synthesised a runtime exit
from a reattach refusal, and it published code `0` — which
`orca-runtime-on-pty-exit` records as `rememberPtyLivenessVerdict(exited)`, a
death certificate whose only legitimate writer is a host-delivered exit frame.
The refusal it acted on is a union. `pty.attach` answers `PTY "<id>" not found`
both for a pid the relay probed with `isProcessAlive` and for an id its session
map simply never had — which, because ids carry a per-start mint epoch, is every
id minted before a relay restart, checked against nothing. So a relay restart
plus a reconnect certified a shell that was still running under the old daemon's
orphaned process tree, retired the pane binding, and cold-started a second agent
onto the same transcript. The sibling `handlePtyReattachFailure` has always
refused to certify from that union; this path did not.
- The relay marks the one refusal it backed with a liveness check
(`PTY_ATTACH_PROVEN_EXITED_MARKER`). The marker is additive, so an unmarked
answer — including an older relay's — stays ambiguous, which is the safe
direction.
- The client mints that half as `SshPtyProvenExitedOnRelayError`, a subclass so
every existing `isSshPtyAbsentFromRelayError` consumer is unchanged.
- Pane adoption publishes `UNVERIFIED_PROCESS_EXIT_CODE` (-1), the sentinel its
sibling publishes, and passes `hostExitConfirmed` only for evidence that
observed the process: the marked relay refusal, or `SessionNotFoundError` from
the registry that owns the PTY. The ambiguous half now records `unverifiable`
instead of `exited`.
- The gone-branch keys on the error type rather than the bare `PTY ".+" not
found` text, so an untyped string can no longer authorise abandoning a
binding — the discriminator `pty-connect-limits.ts` already documented.

* test(pty): make the pane-adoption fixtures throw what real providers throw
These four fixtures rejected with bare `new Error('Session not found: ...')` and
`new Error('PTY "..." not found')`. No provider produces either untyped:
`local-pty-spawn` and `decodeDaemonResponseError` both mint
`SessionNotFoundError`, and the SSH reattach path types the relay's wire text
before any pane sees it. Fixtures that skip the type were the reason a
message-shaped gate looked adequate.
The exit-code expectations move with it: the pane path now publishes the -1
stop sentinel plus `hostExitConfirmed`, so a certificate follows the evidence
rather than a synthesized zero.
