docs(R3-W7): register/roadmap/plan/memory sweep — R3 SHIPPED pending the shared visual pass

AP-78 retired (its condition — App seam bindings + K-fix18 deletion —
landed in W4); TS-21/TS-23/AP-30 anchors re-pinned to the post-W6
controller lines; roadmap + plan record the full W0-W7 trail; the
memory index notes the 2026-06-04 sequencer-deep-dive divergence map
CLOSED by Phase R1-R3. R2+R3 share ONE pending user visual pass; R4
(MoveToManager) is next.
