Major refactor: Fantabeto 26/27 — modular package, GBM ensemble, MILP/MCTS optimization

Phase 1: Data Engineering
- Refactored notebooks into src/{scraper,features,models,optimization,bot}
- FBref scraper with proxy rotation + Playwright Cloudflare bypass
- Fantacalcio.it integrated scraper (authenticated API + HTML fallback)
- api-football RapidAPI client for supplementary xG/xA/injuries
- RAG news pipeline: Gazzetta, Sky Sport, Di Marzio → injury/suspension/tactical extraction
- 26/27 season config: teams, scoring rules, name mappings, news sources

Phase 2: SOTA ML Architecture
- GBM Ensemble (LightGBM + CatBoost + XGBoost) with stacked blending
- Bootstrap ensemble for uncertainty quantification
- SinhArcsinh distribution head (ported from original TF Probability)
- Card classifiers (yellow/red), penalty model, goal probability (Poisson)
- Temporal GNN for player interaction modeling (crosses→goals, passes→assists)
- Optuna hyperparameter tuning with time-series CV

Phase 3: Operations Research
- Auction solver: MILP knapsack with PuLP (budget + role constraints)
- Grid Auction (Asta a Griglia): Minimax game theory bidding strategy
- Weekly lineup optimizer: MCTS maximizing win probability vs opponent
- Modificatore Difesa integration + captain selection
- Transfer market analyzer: buy-low/sell-high via xG regression to mean
- Opponent behavior modeling from historical lineage patterns

Phase 4: Agentic Workflow
- Telegram bot: auto-briefing (Friday + Sunday morning)
- Tactical briefing generator with start/sit recommendations
- GitHub Actions CI/CD: scheduled pipeline (scrape → predict → notify)

Infrastructure:
- 31 pytest unit tests (features, models, scraper, optimization)
- requirements.txt (lightgbm, catboost, xgboost, optuna, pulp, playwright, langchain)
- Makefile with install/test/lint/scrape/train/bot targets
- Jupyter notebook: 26_27_strategy.ipynb demonstrating auction + matchday 1 mockup
- Completely rewritten README.md with architecture diagram

-The aim of this project is to predict Fantacalcio (Serie A fantasy football) player performances (vote and fantavote, respectively their match rating and that summed to the bonus/malus given by goals, assists and cards), using players and teams data from http://fantacalcio.it and http://fbref.com.

-The code has been adapted for <b>Serie-A season 2023/2024</b>, updating the statistics database and taking into account the stats from other leagues, for the players who are at their first season in Serie A (see rookies stats folder).

-![png](README_files/team_predictions.png)
+## Architecture Overview
 
-Two neural network models are trained for predicting vote and fantavote for outfield players and goalkeepers, for which the clean sheet probability is also an output. 
+Fantabeto 26/27 is a complete rewrite of the original 2023/24 codebase, upgraded with production-grade data engineering, state-of-the-art ML models, and advanced optimization algorithms. It predicts **Fantacalcio Modified Scores** (voto + bonus/malus), probabilistic card distributions, goal probabilities, and penalty chances — then generates optimal lineups via Monte Carlo Tree Search.
-The outputs of these models are not raw predictions, but probability distributions, in the form of SinhArcsinh, which is a skewed distribution, meaning that the probability density is asymmetric.
-For predicting clean sheet probability, a Bernoulli distribution is instead used (a sample of which would be clean sheet = 1, with a given probability p, or clean sheet = 0 with probability 1-p)
-
-See the following code and plot to show an example of vote and fantavote probability distributions. 
-In this case, the player would be an attacking one, whose fantavote distribution is very skewed to the right (it is very more probable to score a goal and receive a 10 = 7+3 fantavote, than having an awful performance with a 4 fantavote!).
-
-
-```python
-import numpy as np
-import matplotlib.pyplot as plt
-
-def sinh_archsinh_pdf(x, mu, sigma, eps, delta):
-    mul = 2 / np.sinh( np.arcsinh(2) * delta)    
-    z = (x - mu) / (sigma*mul)            
-    S = np.sinh( -eps + (1/delta) * np.arcsinh(z))
-    return np.exp(-0.5 * S * S) * np.sqrt(1 + S * S) / ( sigma * mul * delta ) / np.sqrt(1 + z * z) / np.sqrt(2 * np.pi)
-
-x = np.arange(start = 0, stop = 30, step = 0.001)
-pxv = sinh_archsinh_pdf(x, 6.06, 0.62, 0.33, 1.06)
-pxf = sinh_archsinh_pdf(x, 5.6657, 1.224146, 0.795868, 1.9983)
-plt.plot(x, pxv, label = 'vote', color = 'b')
-plt.plot(x, pxf, label = 'fantavote', color = 'g')
-plt.fill_between(x, pxv, color = 'lightblue')
