refactor: replace old bot code with Matrix infra configs and scripts

- Remove obsolete Python bot (Wordle, commands, callbacks, welcome)
- Add hookshot/ — all 11 webhook transformation functions + deploy.sh
- Add cinny/ — config.json and dev-update.sh (nightly dev branch build)
- Add landing/ — matrix.lotusguild.org landing page HTML
- Add systemd/ — livekit-server, draupnir, cinny cron unit files
- Add draupnir/ — production config (access token redacted)
