fix(render): iter 92 — verify lmroman/lmromancaps OTF symlinks in PWD

iter 91 DVI capture (dvi-001-1cb0845c.bin) confirmed the pseudo block
(uts-001F's e62c50c.svg) has 7 font_def opcodes:
cmmi10 cmr10 cmsy10 ← working
lmroman10-bold lmroman10-italic lmroman10-regular lmromancaps10-regular ← nf-fallbacks

Tectonic emits these as native XDV font names (not as cmcsc10/cmti10
which is what gh-pages' lualatex+TL2025 emits). The lm package has all
4 OTFs at fonts/opentype/public/lm/ and they're in our targeted symlink
list since iter 59. But the SVG shows nf-fallbacks, so something about
the symlink chain is broken for OTFs.

iter 92 stashes per-file ls -la for these OTFs + a fallback note
'present in FOREST_TEX_DIR but NOT symlinked into PWD' / 'NOT staged'
so we know whether the issue is at the staging step or the symlink step.
