fix: Add GUPP propulsion nudge to daemon restartSession

When Deacon respawns refinery/witness sessions via LIFECYCLE requests,
the new sessions were starting at the Claude welcome screen without
the propulsion nudge that triggers autonomous execution.

Added StartupNudge and PropulsionNudgeForRole calls to restartSession()
in lifecycle.go, matching the pattern used in ensureRefinerySession()
in start.go. This ensures respawned agents receive the GUPP nudge and
begin autonomous work immediately.
