Daemon: replaces a spec that modelled only a client restart and never
crossed the daemon boundary, whose successor generation owned nothing so
"the live successor is neither killed nor replaced" was vacuous. The PTY
leader is now a real login shell reporting `$$` back through the
production write path, resolved to a kernel start time. Two mutations
each redden exactly one of the three clauses, on macOS and Linux:
reverting three-valued `hasPty` reddens only the unknown-not-dead
clause; widening the sole-provider fallback reddens only the stale
generation clause.
Skew: reverting the restore-required publication to expiry reddens 4 of
5 new tests while the legacy control stays green — the regression this
branch fixed is now caught if reintroduced.
Multi-host: restoring `mux.dispose('connection_lost')` reddens sibling
isolation on one host. It does NOT redden across hosts, and that is
recorded rather than glossed: a mux belongs to one relay session per
target, so its dispose cannot cross a host boundary. Journey 4's
cross-host clause rests on isolation-by-construction, not on a mutation.
No production code changes.
