ttf.c: glyph raster cache, fixed slots, no allocation (item 4.3.7d)

Browse Source 
Punch list §25 item 4.3.7d complete. ttf_raster_cache_get() looks up
(font, codepoint, size_px) in a caller-owned fixed slot array, evicting
round-robin once full, rasterizing into a slot on a miss.

Verified live in tools/ttftest.c: an identical (font, 'A', 24px) call
made twice returns was_hit=0 then was_hit=1, and the slot's own hits
counter reads exactly 1 afterward -- checked programmatically. A
different-codepoint call misses again, proving the key actually
discriminates. Wall-clock timing (miss 0.040ms vs hit 0.001ms) is
printed as informational corroboration only, not the load-bearing
check.
