Paul Kloppers 875d6fd6dd add MCP server and Redstone (Gemini) AI assistant ...

Drops two new capabilities on top of the existing Telegram bot + Minecraft
stack, both built around a shared toolkit so there's one source of truth
for the actions either side can take.

mcp/ — a Bun-native MCP server exposing 38 tools to MCP clients (Claude
Code, etc.): server lifecycle, rcon, backup, player/db CRUD, plus 23
Telegram Bot API methods (messaging, reactions, polls, dice, photos,
stickers, pins, forum topics, chat config). Runs over stdio.

mcp/lib/telegram-tools.ts — the Telegram tool catalog as Zod-typed
handlers. Imported by both mcp/server.ts (registers each as an MCP tool)
and bot/bot.ts (exposes each as a Gemini function declaration), so adding
a tool in one place lights it up everywhere.

bot/bot.ts — replaces the silent-on-unknown-text behaviour with Redstone,
an in-bot persona driven by gemini-2.5-flash-lite with native function
calling. In DMs it always responds; in groups only when @-mentioned or
replied to. The tool-use loop (max 4 rounds) lets it decide to send a
poll, react with an emoji, roll dice, etc. via the shared handlers rather
than just text. Thinking budget zeroed and system prompt locked down so
the model doesn't leak its reasoning into replies.

docker-compose.yml — adds google_key as a docker secret and passes
GEMINI_API_KEY_FILE + GEMINI_MODEL to the bot.
