lib_failed_breakdown

Failed breakdown/breakout detection with exhaustion support and resistance levels.

Identifies swing high/low exhaustion points as support/resistance. Detects when price breaks through a level but fails to hold — a failed breakdown (bullish exhaustion signal) or failed breakout (bearish exhaustion signal). These structural signals are key for counter-trend trade activation.

Adapted from Leledc Levels by InSilico:

**Exports:** `detect()` — returns failed BD/BO flags, support/resistance levels, and price action failure signals.
