feat: add quantitative scoring with multi-timeframe analysis and CLI enhancements
Add quantitative scoring pipeline for discovery with technical indicator analysis:
- Momentum, volume, relative strength, and risk/reward scoring
- Support/resistance level detection
- Gap analysis for price momentum signals
- Configurable caching to reduce API calls
Implement multi-timeframe signal analysis:
- Short-term (5/20 day), medium-term (20/50 day), and long-term (50/200 day) signals
- Timeframe alignment detection (aligned_bullish, aligned_bearish, mixed, neutral)
- Signal strength calculation based on indicator agreement
Enhance CLI discovery display:
- Color-coded conviction scores (green/yellow/red thresholds)
- Signal column showing timeframe alignment status
- News mentions count column
Update tests to support new quantitative filtering configuration.
