Rename the intercube all-reduce identity to lrab_hierarchical_allreduce
(module, config key, distributed test) so the name reflects both levels
it implements: LRAB intra-SIP (local reduce to center root + broadcast)
and the hierarchical inter-SIP topology exchange (ring/torus/mesh).
ADR-0032 slug kept as the stable decision id; pure rename, no logic change.
Also in this batch:
- ADR-0032 (EN+KO): document the shipped center-root bidirectional reduce
(doc was stale corner-root); annotate ccl.yaml root_cube as a placeholder.
- Rename allreduce + pe2pe latency plots to descriptive, title-matching
filenames and retitle the in-plot headings; drop overview/overview_log.
- Point the PPTX image refs at the new plot names.
Doc + derived-artifact + rename only; no simulation behavior changed.

scripts/build_overview_slides.py renders a 5-slide PPTX
(kernbench2_overview.pptx) summarizing architecture, model
correctness, IPCQ, allreduce, and buffer-kind tier comparison.
scripts/emit_overview_with_external_ref.py renders log-y and
broken-y variants of the allreduce overview (overview_log.png,
overview_broken.png) including a 366 µs ext-sim reference marker
at 96 KB / PE.
Also includes cube_mesh_view.png rendered from the SVG.
