Detailed Description

OTA Service — Ethernet firmware flash for DiabloAvionics ESP32-S3 boards.

Listens on TCP port 9997 for commands: OTA_FLASH:<board_ip>:<firmware_path> — flash existing .bin to board:3232 OTA_BUILD_FLASH|board_ip|abs_project_dir|board_id — run pio run in abs_project_dir (board_id 1–254 sets PLATFORMIO_BUILD_FLAGS=-DTEMP_HARDCODE_BOARD_ID=N; 0 = no flag), then flash .pio/build/<env>/firmware.bin

Replies: "OK\n" or "ERR:<reason>\n"

Protocol (matches ota-flash.ts):

TCP connect to board_ip:3232
Send 4-byte firmware size (big-endian)
Send .bin in 4 KB chunks
Read "OK" in response before board reboots

Usage: ./ota_service [–port PORT]
