Preserve backup_old_docker bot variant at root (for comparison)

Snapshot of the dockerisation-era bot code laid out at the repository
root so it can be diffed directly against the working-copy baseline
(restructure/working-copy-root) to see how the variant differed:

- thin_client.py asyncio entrypoint (vs working_copy bot.py)
- constants.py env-var/credential refactor, communication auth, etc.
- extra gpt_interface/ service, sync.py, watch_script_params.py
- conanjurer_* modules absent in this variant

Docker infrastructure (docker/, docker-compose.yml, .dockerignore)
intentionally omitted - this branch is for code comparison only and is
not intended to be merged.
