Function main_client_bootstrap_with_upgrade

src/main.c:1490–1518

Client bootstrap with the upgrade policy: a CONFLICT against a PERMANENT * daemon of a strictly OLDER release is resolved by draining that daemon * (the same authenticated path install/update use) and retrying once. A * manual binary swap therefore self-heals exactly like the ephemeral * lifecycle used to, instead of deadlocking behind the pinned daemon. Same- * or newer-build daemons and dev

 * lifecycle used to, instead of deadlocking behind the pinned daemon. Same-
 * or newer-build daemons and dev builds are never auto-drained. */
