Get detailed analysis for a specific asset (coin or stock) on specified exchange and timeframe.

    This is the canonical single-symbol technical readout (there is no
    "get_technical_analysis" or "get_technical_summary" tool — use THIS one).
    Use `multi_timeframe_analysis` instead when you need trend alignment
    across several timeframes, and `combined_analysis` when you also want
    news sentiment + headlines in the same call.

    Example: coin_analysis(symbol="BTCUSDT", exchange="BINANCE", timeframe="1h")

    Args:
        symbol: Bare ticker, no exchange prefix — crypto: "BTCUSDT", "ETHUSDT"; stocks: "COMI" (EGX), "THYAO" (BIST), "600519" (SSE), "300251" (SZSE), "2330" (TWSE), "3105" (TPEX)
        exchange: Exchange — crypto: KUCOIN, BINANCE, MEXC; stocks: EGX, BIST, NASDAQ, NYSE, BURSA, HKEX, SSE, SZSE, TWSE, TPEX. If the symbol isn't listed there, the error's `listed_on` field names exchanges that do list it.
        timeframe: Time interval (5m, 15m, 1h, 4h, 1D, 1W, 1M)

    Returns:
        Detailed analysis with all indicators and metrics
