docs: Record V1.2.6 in Script A's history and add the release note

Browse Source 
Script A: header to V1.2.6; entries for blanton_fdr.sh, the unused
lanes off in Script A, and the FDR hooks in Script A, B and C, with
notes on the unverified STOp keyword, the lanes never being turned
back on, the both-units-only gating and the exec bits.

CLAUDE.md / ARCHITECTURE.md: status and release to V1.2.6, FDR and the
unused lanes in the overview, the Script A flow, the tree and the
commands.

; !! nothing turns them back on: no 'unused_lanes.sh on' in
; Script C. They stay off until 'unused_lanes.sh on' is run
; by hand (whether a reboot clears them is not checked)
; !! not gated by SWB_UNIT0 / SWB_UNIT1 - always both units
