feat: initial Minecraft Bedrock AI Bridge MCP server

MCP server that bridges Minecraft Bedrock Edition's WebSocket API
to Claude Code CLI. Exposes 6 tools: minecraft_command, minecraft_chat,
minecraft_build, minecraft_get_events, minecraft_get_status, minecraft_subscribe.

Supports both SSE and Streamable HTTP MCP transports.
Privacy-first: no disk persistence, no telemetry, memory-only event buffer.
