feat: Add MA crossover detection to n8n workflow
- Updated parse_signal_enhanced.json to detect 'crossing' keyword - Added three new flags: isMACrossover, isDeathCross, isGoldenCross - Death cross = MA50 crossing below MA200 (short direction) - Golden cross = MA50 crossing above MA200 (long direction) - Enables automated data collection for MA crossover pattern validation - Documented in INDICATOR_V9_MA_GAP_ROADMAP.md validation strategy - User configured TradingView alert to send crossover events - Goal: Collect 5-10 examples to validate ADX weak→strong pattern
