Add benchmark log table to development-status.md comparing:
- a201594: extract_dup+from_buffer_copy (2 copies, 6MB/frame) → 36.5ms, 87.6% budget
- da02e74: buffer.map+memmove into reusable ctypes array (1 copy, 3MB/frame) → 33.6ms, 80.5% budget
Note that the 3.1MB memmove is now the remaining bottleneck and further
reduction would require DMA-buf zero-copy via kernel VPU driver support.
Update next actions: profile SDL upload overhead, explore dmabuf fd path,
and consider 720p downscale option if stutter appears under combined load.
