Pull deps image on ARM when unchanged, add push retry (#63)

* Upgrade ARM CI instances to m8g.xlarge and add push retry logic

t4g.large was causing Docker daemon crashes due to resource exhaustion
during ARM builds, leading to failed image pushes (EOF on docker socket).

* Address Copilot review: redirect push output to log file and skip sleep after final retry
