fix(render): iter 85 — pivot to rm-*.tfm + verify VF chain shim presence
Iter 84's surgical psfonts.map strip worked at the file level
(verified: 1 cmcsc10 entry pointing direct to cmcsc10.pfb), but the
SVG bytes didn't change. Reread the warnings log — the loud failures
are NOT 'cmcsc10.pfb not found' (we have it staged) but:
WARNING: can't find rm-lmb10.tfm
WARNING: can't find rm-lmr{6,7,9,10}.tfm
WARNING: can't find rm-lmri{7,10}.tfm
These rm-*.tfm files DO exist in lm.tar.xz under fonts/tfm/public/lm/
and our stage_tl_pkg flat-copies all *.tfm — so they're on disk in
both FOREST_TEX_DIR AND FOREST_TEXMF tree, but kpathsea can't find
them at dvisvgm runtime.
Iter 85 verifies their presence in both stores and rebuilds ls-R
cache to make sure it's indexed before build runs (not after).

# iter 85 — the actual root cause for ag-0018's overlap (per iter 84
633
+
# warnings) is dvisvgm's "can't find rm-lmb10.tfm" / rm-lmr*.tfm /
634
+
# rm-lmri*.tfm errors during the VF chain expansion. Those rm-*.tfm
635
+
# files ARE in lm.tar.xz at fonts/tfm/public/lm/ — stage_tl_pkg's
636
+
# flat copy puts them in FOREST_TEX_DIR (already verified) AND
637
+
# FOREST_TEXMF (also already). So they're on disk but kpathsea
638
+
# somehow can't find them.

#
640

# Hypothesis: ls-R cache wasn't built when forester first ran (iter
641
+
# 83's rebuild happens AFTER psfonts.map agg but maybe AFTER the
642
+
# build runs too?). Rebuild ls-R BEFORE the build step, and dump
643
+
# it to /tmp for inspection.
