GlyphStripCache class
LRU cache of rasterized glyph strips, replayed by StripGenerator.fillOutline.
Keys are (immutable outline identity, quantized matrix), so entries never go stale - the caps just bound memory. One instance is safe to share across generators on the same isolate (shared is the default); entries retain their FlattenedOutline keys, so a hard clear releases font memory if needed.
