Switched internal Pod runtime spawning/restoration to typed program + prefix_args command resolution. Default runtime command now uses the current executable plus pod, while INSOMNIA_POD_COMMAND remains executable-only and not shell-parsed for development/debug overrides. client::spawn_pod, SpawnPod, and RestorePod/discovery restore paths use the typed command; detached process behavior and INSOMNIA-READY handshake are preserved. External review approved and validation passed. insomnia-pod packaging removal remains the next phase.
