feat: add NoDL column to --list

-l now shows a NoDL column (✓ when the hint has NODOWNLOAD=yes) next to
the existing DelReq column. Detected via grep -qi '^NODOWNLOAD=yes',
padded with _pad_glyph for multibyte alignment.

Tests T68/T69 cover populated and blank NoDL. Docs (CLAUDE.md, README,
man page) updated and mkhint.1.gz rebuilt.
