v2 architecture draft: see `docs/architecture-v2.org`

default v2 app run:
```
python3 ./youdis.py
```

direct component runs still work for testing:
```
python3 -m uvicorn youdis.main:app --host 127.0.0.1 --port 8000
python3 -m youdis.adapters.discord
```

build and run the docker container
```
DISCORD_BOT_TOKEN = [discord bot token]
-v [downloads]:/downloads
-v [config]:/config
```
config contains data to persist across container updates, i.e., unraid appdata, 
such as yt-dlp's archive.txt
