Subject: [PATCH] [esp32_hosted] Replace set_retry with set_interval to avoid
 heap allocation

set_retry internally does a std::make_shared<RetryArgs>() heap allocation
on every invocation. Replace with set_interval + countdown counter which
avoids this entirely. The original code used fixed-interval polling
(no backoff), making set_interval a direct fit.
