Memory profiling via Valgrind Massif indicated that 10-20% of peak memory allocations within the SNI loop resulted from copying DBus image data payloads via g_memdup2 before modifying them from ARGB to RGBA.
This commit optimizes the pixel conversion by directly allocating the final array via g_malloc and running the ARGB->RGBA transposition in a single pass while copying from the read-only GVariant buffer, entirely eliminating the intermediate g_memdup stage.
