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)

+#   ./deploy.sh proxmox.js       # deploy one hook

+# Requirements:
+#   MATRIX_TOKEN  - access token with power level >= 50 in the target room
+#   MATRIX_SERVER - homeserver URL (default: https://matrix.lotusguild.org)
+#   MATRIX_ROOM   - room ID where hooks are registered
