Debug Builds: the console over Wi-Fi (Debug Console, TCP 2323)

cardputer-adv-debug (-DRORO_DEBUG, version +debug) adds a Debug Console:
after a token line, a client gets the last 6 KB of console output, live
lines (ESP-IDF logs included) and the serial commands. The socket task
only queues lines; the main loop runs them. Release builds compile none
of it. The token lives in ~/.config/roro9stack/debug-token, created by
_docker.sh and passed into the container.

All output now goes through `console`, which never waits for USB: a host
that was attached but not reading stalled the main loop up to 2 s per
line. New commands everywhere: info (slots with their versions from NVS,
since the framework stamps its own into each image), tasks, reboot,
boot other, log level, help. scripts/rdbg.py is the client; flash.sh
--debug builds it; CI builds both variants. ADR 0004.

Verified on the device: USB-flashed, then updated over Wi-Fi to a Debug
Build that confirmed on Probation; both slots hold Debug Builds.
