* controller: enable the DualSense HIDAPI driver, light bar and adaptive triggers
Three additions. SDL was opening a DualSense through the generic gamepad path, so SDL_GameControllerHasLED and SDL_GameControllerGetNumTouchpads both reported nothing and no touchpad events ever arrived - enabling the PS5 HIDAPI driver before SDL_InitSubSystem is what makes the light bar and the existing touchpad support reachable. PadSetLightBar validated its arguments and returned OK without touching the pad; it now drives the LED. PadSetTriggerEffect did the same; it now translates the mode and parameters into a DualSense trigger block and sends it.

* 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
