feat: discovery pipeline enhancements with ML signal scanner

Major additions:
- ML win probability scanner: scans ticker universe using trained
  LightGBM/TabPFN model, surfaces candidates with P(WIN) above threshold
- 30-feature engineering pipeline (20 base + 10 interaction features)
  computed from OHLCV data via stockstats + pandas
- Triple-barrier labeling for training data generation
- Dataset builder and training script with calibration analysis
- Discovery enrichment: confluence scoring, short interest extraction,
  earnings estimates, options signal normalization, quant pre-score
- Configurable prompt logging (log_prompts_console flag)
- Enhanced ranker investment thesis (4-6 sentence reasoning)
- Typed DiscoveryConfig dataclass for all discovery settings
- Console price charts for visual ticker analysis

+# ML Win Probability Model — TabPFN + Triple-Barrier
+
+## Overview
+Add an ML model that predicts win probability for each discovery candidate.
+- **Training data**: Universe-wide historical simulation (~375K labeled samples)
+- **Model**: TabPFN (foundation model for tabular data) with LightGBM fallback
+- **Labels**: Triple-barrier method (+5% profit, -3% stop loss, 7-day timeout)
+- **Integration**: Adds `ml_win_probability` field during enrichment
+
+## Components
+
+### 1. Feature Engineering (`tradingagents/ml/feature_engineering.py`)
+Shared feature extraction used by both training and inference.
+20 features computed locally from OHLCV via stockstats + pandas.
+
+### 2. Dataset Builder (`scripts/build_ml_dataset.py`)
+- Fetches OHLCV for ~500 stocks × 3 years
+- Computes features locally (no API calls for indicators)
+- Applies triple-barrier labels
+- Outputs `data/ml/training_dataset.parquet`
+
+### 3. Model Trainer (`scripts/train_ml_model.py`)
+- Time-based train/validation split
+- TabPFN or LightGBM training
+- Walk-forward evaluation
+- Outputs `data/ml/tabpfn_model.pkl` + `data/ml/metrics.json`
+
+### 4. Pipeline Integration
+- `tradingagents/ml/predictor.py` — model loading + inference
+- `tradingagents/dataflows/discovery/filter.py` — call predictor during enrichment
+- `tradingagents/dataflows/discovery/ranker.py` — surface in LLM prompt
+
+## Triple-Barrier Labels
+```
++1 (WIN):     Price hits +5% within 7 trading days
+-1 (LOSS):    Price hits -3% within 7 trading days
+ 0 (TIMEOUT): Neither barrier hit
+```
+
+## Features (20)
+All computed locally from OHLCV — zero API calls for indicators.
