* fix(terminal): stop transient probe blips from erroring restored panes (STA-3536)
terminal_pane_owner_unverified fired for every restored pane whenever one
liveness probe answer went missing: a cold-start daemon draining an attach
stampede misses the 2s getSize deadline, and a wedged superseded daemon
(protocol upgrades leave them running) turns every unmapped fan-out probe
null forever.
- probePtyOwners now skips legacy daemons whose startup inventory listing
succeeded: fresh sessions never route to them, so they provably don't own
an unmapped id and one wedged zombie can't poison every pane's verdict.
- attachStablePaneOwner retries the probe over a short backoff ladder before
surfacing unverified, so a single missed deadline resolves to a verdict.
- The renderer replaces the raw error code with actionable copy.
* fix(terminal): stop retrying definitive owner probes
* fix(terminal): recover live panes after renderer restart
* refactor(terminal): share owner resolution abort guard
