Integrate matrixbot into existing LXC 151 deploy hook

Removed standalone matrixbot/deploy.sh — deploy is handled by the existing
webhook system. Added matrixbot/ block to deploy/lxc151-hookshot.sh: on push,
if any matrixbot/ file changed, source files are synced to /opt/matrixbot and
matrixbot.service is restarted automatically.

+# Lotus Matrix Bot & Server Roadmap
+
+Matrix bot and server improvements for the Lotus Guild homeserver (`matrix.lotusguild.org`).
+
+**Repo**: https://code.lotusguild.org/LotusGuild/matrixBot
+
+## Status: Phase 3 — Bot Features & SSO
+
+---
+
+## Priority Order (suggested)
+1. ~~PostgreSQL migration~~
+2. ~~TURN server~~
+3. ~~Room structure + space setup~~
+4. ~~Matrix bot (core + commands)~~
+5. ~~LiveKit / Element Call~~
+6. ~~SSO / OIDC (Authelia)~~
+7. Custom Element Web (chat.lotusguild.org with branding)
+8. Discord bridge (lets people transition gradually)
+9. Custom emoji packs (makes it feel like home)
+10. Moderation bot
+11. Everything else
+
+---
+

+## Rooms (all v12)
+
+| Room | Room ID | Join Rule | Bot In |
+|------|---------|-----------|--------|
+| The Lotus Guild (space) | `!gSynpxmopNrtoxeSvj` | public | — |
+| General | `!wfokQ1-pE896scu_AOcCBA2s3L4qFo-PTBAFTd0WMI0` | public | no |
+| Welcome | `!Y-wvNosuytqBOWampH9k-ta7bYXW7okqwBQ7PuRVBWE` | public | yes |
+| Commands | `!ou56mVZQ8ZB7AhDYPmBV5_BR28WMZ4x5zwZkPCqjq1s` | restricted | yes |

+| Cool Kids | `!R7DT3QZHG9P8QQvX6zsZYxjkKgmUucxDz_n31qNrC94` | invite | no |
+
+**Power level roles (Cinny tags):**
+- 100: Owner (jared)
+- 50: The Nerdy Council (enhuynh, lonely)
+- 48: Panel of Geeks
+- 35: Cool Kids

+
+---
+
+## Server - Quality of Life
+- [x] Migrate from SQLite to PostgreSQL
+- [x] Set up TURN/STUN server (coturn) for reliable voice/video calls behind NAT
+- [x] Enable URL previews in Synapse
+- [x] Increase upload size limit for media/GIFs (200MB)
+- [x] Enable message search (full-text search with PostgreSQL backend)
+- [x] Configure media retention policy (remote: 1yr, local: 3yr)
+- [x] Set up sliding sync (native in Synapse, no proxy needed)
+- [x] LiveKit server with systemd service for Element Call video rooms
+- [x] Default room version set to v12, all rooms upgraded
+- [x] Room publishing rules (jared + lotusbot can publish to directory)
+- [ ] Enable push notifications gateway for mobile clients
+
+## Server - Auth & SSO
+- [x] Token-based registration (registration tokens shared in Discord)
+- [x] SSO/OIDC via Authelia (`oidc_providers` in homeserver.yaml)
+- [x] `allow_existing_users: true` for linking existing accounts to SSO
+- [x] Password auth remains enabled alongside SSO
+
+## Server - Hardening
+- [x] Rate limiting configuration in Synapse
+- [x] E2EE enabled on all rooms
+- [ ] Federation allow/deny lists (decide if you want open federation or Lotus-only)
+- [ ] Regular Synapse version updates
+- [ ] Monitoring with Prometheus + Grafana
+- [ ] Synapse worker mode if performance becomes an issue
+
+## Server - Admin & Moderation
+- [x] Synapse admin API dashboard (synapse-admin v0.11.1 at http://10.10.10.29:8080)
+- [x] Power levels configured per room (Cinny tags for role hierarchy)
+- [x] Invite-only registration flow (token-based)
+- [ ] Set up Mjolnir or Draupnir (moderation bot for ban lists, spam protection)
+- [ ] Set up room ACLs for federation control (block known-bad servers)
+- [ ] Automated backups of Synapse database and media
+
+## Bridging (Transition Period)
+- [ ] Set up mautrix-discord bridge so messages flow between Discord and Matrix
+- [ ] Bridge key channels (general, gaming, memes, etc.)
+- [ ] Bridge voice channels if possible (experimental, may not be worth it)
+- [ ] Puppet bridging so Discord users appear as Matrix users and vice versa
+
+## Room Structure
+- [x] Set up "The Lotus Guild" space as top-level container
+- [x] General, Welcome, Commands, Management, Memes, Cool Kids rooms
+- [x] Welcome room with react-to-join onboarding
+- [x] Bot commands room (Commands — keeps bot spam contained)
+- [x] Voice/video call room (Element Call via LiveKit)
+- [x] Custom room avatars with Lotus Guild branding
+- [ ] Sub-spaces for categories (Gaming, Media, etc.)
+- [ ] Read-only announcements room
+- [ ] Game-specific rooms (Minecraft, Valorant, League, Hytale, etc.)
+
+## Custom Emoji & Stickers
+- [ ] Export all custom emojis from Discord server
+- [ ] Create Matrix emoji packs (per-room or space-wide)
+- [ ] Set up sticker picker widget in Element
+- [ ] Import/create Lotus Guild sticker pack
+
+## Element/Client Customization
+- [x] Landing page at matrix.lotusguild.org with client recommendations (Cinny, Commet, Element)
+- [ ] Custom Element Web instance (self-hosted on chat.lotusguild.org)
+- [ ] Custom theme with #980000 branding
+- [ ] Configure .well-known to point clients to custom Element Web instance
+
+## Widgets & Integrations
+- [ ] RSS bot for game news feeds
+- [ ] GitHub/Gitea notifications bot (push events to a dev room)
+
+---
+
+## Bot - Core Setup
+- [x] Project scaffolding (`bot.py`, config, `.env`, requirements)
+- [x] matrix-nio async client with E2EE support
+- [x] Device verification / trust storage (auto-trust all devices)
+- [x] Logging (rotating file + stdout)
+- [x] Config validation (homeserver URL, access token, device ID)
+- [x] Graceful shutdown handling (SIGTERM/SIGINT)
+- [x] Initial sync with startup token (ignores old messages)
+- [x] Auto-accept room invites
+
+## Bot - Commands (all implemented)
+- [x] `!help` — List all available commands
+- [x] `!ping` — Bot latency check
+- [x] `!8ball <question>` — Magic 8-ball
+- [x] `!fortune` — Fortune cookie message
+- [x] `!flip` — Coin flip
+- [x] `!roll <NdS>` — Dice roller
+- [x] `!random <min> <max>` — Random number generator
+- [x] `!rps <choice>` — Rock Paper Scissors
+- [x] `!poll <question>` — Poll (reactions)
+- [x] `!trivia` — Trivia game (reactions, 30s reveal)
+- [x] `!champion [lane]` — Random LoL champion picker
+- [x] `!agent [role]` — Random Valorant agent picker
+- [x] `!wordle` — Full Wordle game (daily puzzles, hard mode, stats, share)
+
+## Bot - Integrations
+- [x] `!minecraft <username>` — RCON whitelist
+- [x] `!ask <question>` — Ollama LLM integration (lotusllm, 2min cooldown)
+
+## Bot - Admin Commands
+- [x] `!health` — Bot stats (uptime, command counts, service status)
+
+## Bot - Welcome System
+- [x] Auto-post welcome message in Welcome room on startup
+- [x] React-to-join: users react with checkmark, bot invites to General, Commands, Memes
+- [x] Welcome message event ID persisted to `welcome_state.json`
+- [x] Reaction handler via `UnknownEvent` callback for `m.reaction` events
+
+## Bot - Wordle
+- [x] Daily puzzles with proper two-pass letter evaluation
+- [x] Hard mode with constraint validation
+- [x] Statistics tracking with persistence (`wordle_stats.json`)
+- [x] Cinny-compatible rendering (inline `<span>` tiles instead of `<table>`)
+- [x] DM-based gameplay (games happen in DMs, `!wordle share` posts to public room)
+- [x] Virtual keyboard display with letter state tracking
+
+## Bot - Deployment
+- [ ] Systemd service (`matrixbot.service`)
+- [ ] Auto-deploy from Gitea webhook
+- [ ] Deployment script
+- **Bot lives in**: Welcome (react-to-join) and Commands (all commands)
+
+## Bot - Not Porting (Discord-specific)
+- Reaction roles (replaced by react-to-join in Welcome room)
+- Status cycling (Matrix presence is simpler)
+- Guild-specific event handlers (channel create/delete, boost, etc.)
+
+---
+
+## Tech Stack
+- **Language**: Python 3
+- **Library**: matrix-nio (with E2EE)
+- **Homeserver**: matrix.lotusguild.org (Synapse on 10.10.10.29)
+- **Database**: PostgreSQL 17 on 10.10.10.44
+- **TURN**: coturn on 10.10.10.29 (colocated with Synapse)
+- **LiveKit**: livekit-server on 10.10.10.29 (systemd, public IP 162.192.14.139)
+- **SSO**: Authelia on 10.10.10.36 (OIDC provider, backed by LLDAP)
+- **Dependencies**: matrix-nio[e2ee], aiohttp, python-dotenv, mcrcon
