Adjacent-stage recurrence obtained by applying the paper move chain at every nonterminal stage.

The paper-total stage-mass telescope for fromHToG.

This follows the iteration in ld-pasting.tex:1354--1372: applying the adjacent-stage estimate over all k stages gives k copies of the per-stage error. Lean records that literal telescope before the final scalar bound fromHToGPaperTotalError_le absorbs it into fromHToGError.
