Build DOE-PERSIST-TRIAL: block-backed DoE campaign persistence, live-verified

Browse Source 
FABRIC-3.md §XXXV.3/.4 designed this and it was never built -- two live
campaigns got launched relying entirely on a live serial-log tail before
this was caught. doe_region.c/.h mirrors log_region.c's own growable-ring
pattern (own devblock_from_top fence at 98, past log_region's ceiling at
97) to persist one trial-summary record per completed trial straight to
disk/artemis.img, surviving past QEMU exit with no host required.

Verified end to end: booted amd64, called DOE-PERSIST-TRIAL at the
console, clean BYE, then read the raw disk bytes back with QEMU fully
dead -- confirmed the exact values passed in. Wired into both
multiuser-doe.4th and per-isa-doe.4th's trial markers. Clean build, zero
new warnings, all 3 ISAs; mkcapsule --lint passes both edited capsules.

FABRIC-3.md §XXXV.10 documents the fix and the root-cause correction: two
campaigns were launched on an unbuilt persistence design before this was
caught and fixed.
