e0test: check-exchange acceptance stage for edit 6; record RC1 first-light

Browse Source 
After the flip leaves counters over threshold, the tool now sends a
CheckRequest (ACKing every status frame) — edit-6 chips must repaint
and re-render the E0 readout; 04000000 marks a pre-rc1 chip. Analysis
records the stock-chip archaeology (stock also leaves 04000000, but the
ungated E0 readout papered over it in period — our fixes exposed it)
and RC1's below-threshold first-light PASS (version+check -> F0).
