TyrianGbaPoc v71 - UNDERDELI Blur Pixelation Fix
Fixes the coarse 2x2 pixelation seen when save slot 2 enters Episode 4 UNDERDELI. Root cause: the PC temporal blur event was incorrectly approximated with GBA hardware Mosaic across all world BGs and OBJs. The source event and telemetry remain intact, while the distortion-causing Mosaic path is removed. Targeted validation: TGRS pass=1, assets valid, zero background stream drops, zero background cache approximations, zero Sprite2 decode/cache drops, and zero projectile cache drops.
