test(stick): Artemis grows to fill the stick -- the tests, seen to fail (#92, Task 2) [skip ci]

Browse Source 
Plan 2026-10-29-stick-5, Task 2, steps 1-2:
- qemu_session.py: --stick-gib N (the session's copy of the stick extended,
  sparse); modes stick_grow (16 GiB: grown, over 12000000 user blocks, the
  prompt, the first boot's time; the second boot of the same copy not grown
  again; sfdisk --verify clean) and stick_small (4 GiB: under 8 GB, not grown,
  said so).
- kernel/Makefile: STICK_GIB and STICK_FRESH on qemu-stick, for those.
- check_images.sh: the PC stick's and data stick's Artemis BAM sized for the
  256 GiB cap (6144 devblocks).

Before the change: stick_grow FAIL (no growth line, 1137649 user blocks,
sfdisk: the backup GPT not at the end); stick_small FAIL (no line);
check_images.sh FAIL on the two BAM checks only.
