Log Message:
syncdoom: add sixel to the F4 tier cycle on JXL terminals

When JXL is the startup tier, the door now also probes sixel (the JXL
ladder short-circuits before probe_sixel, and a JXL-capable SyncTERM
answers the sixel CTDA query immediately), and adds it as a second
graphics state so F4 cycles jxl -> sixel -> text tiers. Lets a player
A/B the two graphics tiers live. Skipped when sixel is force-disabled.

Graphics-tier cycle labels now name the tier (jxl/sixel/ppm) instead of
the generic "graphics", so the F4 flash shows which one you're on.
