font: full mixed-case + punctuation glyph set (not uppercase-only)

Replace the small-caps placeholder font with a real baseline-aligned
4x8 set covering all 96 printable ASCII: distinct lowercase with true
ascenders (b d f h k l t) and descenders (g j p q y), digits, and
punctuation. Metrics: caps/ascenders rows 1-5, x-height rows 2-5,
baseline row 5, descenders into rows 6-7. Glyphs are ~3px wide in the
4px cell -- cramped but legible; the tile mechanism itself imposes no
character-set limit.

genfont.py now takes per-glyph (top, rows) so glyphs sit on the baseline.
Demo strings in term_test updated to show mixed case + punctuation.
Verified by screenshot: descenders visibly drop below the baseline.
