Multi-timeframe alignment analysis (Weekly → Daily → 4H → 1H → 15m).

    Canonical name is exactly `multi_timeframe_analysis` (there is no
    "get_multi_timeframe_analysis" tool). Use this for cross-timeframe trend
    alignment on ONE symbol; for a single-timeframe deep dive use
    `coin_analysis`; for TA + sentiment + news use `combined_analysis`.

    Example: multi_timeframe_analysis(symbol="SOLUSDT", exchange="BINANCE")
