SPI clock speed between ESP32-C3 and GD32E50x.

Higher value speeds up GD32 OTA relay, but must be

validated against actual wiring length/quality and GD32
|

|
|
SPI slave timing.

Idle delay inserted after each successfully acknowledged

Lower value speeds up OTA, but if GD32 cannot finish

flash write / prepare next ACK in time, set it back.

Delay between SPI response polls when GD32 returns WAIT

idle time and can significantly speed up OTA, but if GD32

cannot finish flash write before the next poll, increase it.

How long ESP32 waits for GD32 to respond to the FINISH_OTA

command. GD32 may need extra time to drain flash buffers,

verify firmware, or prepare the APP jump.
