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.

The pe2pe overview compared IPCQ (tl.send + tl.recv) against raw DMA
(tl.load + tl.store), but DMA is one-sided — DST never reads — while
tl.recv pays a slot-read on DST. The comparison was unfair: IPCQ
looked slower partly because it does more work.
Adds tl.recv_no_consume() — a separate, diagnostic-only entry point
that blocks for slot arrival but skips the slot-read (and bank-hop)
charge on DST. Production tl.recv is unchanged (no `consume` kwarg
on the public API), so the diagnostic flag can never accidentally
leak into real workloads.
Updates test_pe_to_pe_latency to call tl.recv_no_consume so the
overview.png shows IPCQ no-consume vs raw DMA on equal footing.
Also fixes PLOT_DIR back to docs/diagrams/pe2pe_latency_plots/
(was lost in a merge). Adds scripts/replot_pe2pe.py for label-only
re-renders without re-measuring.
