Delete USDT-M futures support since the user's Binance API key does not support futures trading. This simplifies the CLI to spot-only: - Remove futures client wrapper (um_futures_client.py) - Remove futures trade commands and close position logic - Simplify account service to spot-only (no market_type field) - Remove futures references from opportunity service - Update README and tests to reflect spot-only architecture - Bump version to 2.0.7 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
