fix(boot): base submodule ptr (bare/mini warning cleanup) + bare serial console

Track base 1769b083 (condition_path_exists for optional daemons, ahcid no-media,
netstack no-NIC idle, dhcpd fast-fail). Re-enable the serial debug console on
the bare target so it has a headless-visible login prompt (matching mini up to
login).

+# NOTE: the serial debug console (31_debug_console.service, getty on

+# minimal.toml) on the bare target. It is the only login prompt visible on a
+# headless serial console, which is exactly how a "bare" boot-test image is
+# driven (QEMU -serial stdio, real serial header on bare metal). The earlier
+# concern about a ~45s getty retry hang applied to the minimal 6-daemon initfs
+# that did not run ptyd; the bare target now switchroots into the full rootfs
+# where ptyd is running, so the debug console comes up immediately.
