Functions
void	gpu_usage_init (GPUUsageMonitor *mon)
	Scans /proc/self/fdinfo/ and opens streams for GPU engine time reading.
void	gpu_usage_cleanup (GPUUsageMonitor *mon)
	Closes all open fdinfo streams.
void	gpu_usage_update (GPUUsageMonitor *mon)
	Re-reads fdinfo streams and computes GPU load %. Should be called periodically (e.g., every 500ms).
float	gpu_usage_get_load (const GPUUsageMonitor *mon)
	Returns the last computed GPU load (0.0–100.0).
bool	gpu_usage_is_available (const GPUUsageMonitor *mon)
	Returns true if a supported DRM driver was detected.
