* renderer: decode R32_SFLOAT packed colour clears
DecodePackedColorClear handled R32Uint, R32Sint and the 8/10-bit formats but fell through to the default false case for R32Sfloat. metadata_clear_supported then went false, the clear value was discarded, and the target kept its previous contents. Decode the packed word as float bits, matching DecodePackedDepthClear directly below, and reject non-finite patterns rather than materializing them.
* renderer: preserve all R32_SFLOAT clear bits
