Test print start: guard peaks 1-8 in every phase except the brush scrub
(peak 47, 4 reads above 30 in a row), 0 I2C errors; a light finger push
gives 41. Stop mode for all phases, the brush stays log-only.
The contact homing in HOME restarted 6 times (sample spread too large)
while the nozzle was still heating to 150C; PRINT_WARMUP now waits for a
steady contact temperature first, as PRINT_START does.
