Sonic SMS v0.0.4 - native HLE and faithful 16x

Native CPU/event execution, exact PSG block synthesis and faithful 16x GPU rendering. Original tile pixels stay sharp with no smoothing or invented detail. The GPU consumes resident tile-row jobs; enhanced resolution does not require a CPU enhanced framebuffer or scale-dependent uploads.

The packaged Windows x64 build preserves the existing assisted coverage: all29 routes execute without fallback and all89 rendered native/interpreter checkpoints agree. The final6000-frame route has exact state/timeline/PCM against the qualified native checkpoint; every16x pixel matches native output. Owner visual checks passed. This remains a pre-release with assisted coverage, not a claim of a complete unassisted playthrough.
