docs(triage): sync branch to master so pillar anchors resolve in-tree; cite #200 §1

Addresses Codex review on PR #201: src/hpc/pillar/{ewa_sandwich_2d,
ewa_sandwich_3d,splat_invariants}.rs were absent from this branch's tree
because the branch was cut from a pre-pillar/ master point. The files are
real on master and independently confirmed by the merged #200 audit §1.
Merged origin/master in (non-destructive) so every cited anchor now
resolves on the branch, and added a note pointing to #200 §1 as the
branch-independent witness.
