🤖 Play against KataGo

[Terkwood]

Goal

Implement a system which allows playing against a KataGo instance running on an NVIDIA Jetson Nano.

Background

We picked up an NVIDIA Jetson Nano board and built KataGo. Documentation is available in the repo now

Tasks

• build KataGo on the nano
• wrap katago stdin/stdout Wrap KataGo stdin/stdout #190
• make a basic docker image Create docker image for KataGo Jetson Nano build #189
• gateway: backend routing (Gateway: send commands to both backends #205)
• gateway: send & recv bot attachment and move-making messages
• use websockets correctly Use tokio to split ws send and recv #210
• create botlink service and push game states via websocket (📠 Create botlink service  #193, 🛰️ Add botlink service 🛰️ #196, Add bot communication model #197)
• connect tinybrain to Botlink service via websocket and process game states (Add websocket support to tinybrain #194)
• document reverse-proxy setup
• clean up micro-changelog init (Remove game-ready reader from micro-changelog  #187)
• extend Sabaki initial menu, send attach bot command, process makemoves as normal, listenForMove when human plays white

Just played the first game against KataGo using our system. They won ;)
