fix(render): iter 87 — add CM fonts + rm-lm* VF shims to targeted symlink list (the actual lookup path dvisvgm uses)

iter 86 was the breakthrough: kpsewhich could NOT find ANY font in our setup
(including lmr10.pfb which renders fine in production). That means dvisvgm
isn't using kpathsea/TEXMF lookup at all at runtime — it reads from
PWD (cwd) where the iter-58/59 targeted symlink list places SPECIFIC font
files. Everything we added to FOREST_TEX_DIR / FOREST_TEXMF / psfonts.map /
ls-R was IRRELEVANT.

The targeted symlink list hand-curated which fonts get symlinked from
FOREST_TEX_DIR into forester's MAIN cwd $PWD. Missing from the list:
cmcsc10, cmti10, cmr10/7, cmbx10, cmmi10/7, cmsy10/7, plus the rm-lm* VF
shim TFMs that dvisvgm tries to load for the LM-rep fallback chain.

Adding all of them now. If iter 87 lands, ag-0018 should switch from
nf2/3/5/7 -> cmcsc10/cmti10 (and the operator sees the overlap go away
in their browser).
