v0.85.0

Added

• MCP endpoint for AI agents (Discussion #429) — Yuvomi now serves a stateless Model Context Protocol endpoint at /mcp (JSON-RPC 2.0 over HTTP). AI clients such as Claude Desktop can list and create tasks, shopping items, and calendar events through natural language. It authenticates with the existing API tokens (Authorization: Bearer <token>), so no new environment variable, port, or setup step is required.
