Build a final league table with abandoned matches, a forfeit, a points deduction and head-to-head tie-breaks

# Final league table with tie-breaks Inputs: `matches.csv` (every fixture of a double round-robin season, with status) and `sanctions.csv` (points deductions). Produce the final table. - Points: 3 for a win, 1 for a draw, 0 for a loss, minus any deduction in `sanctions.csv`. - An abandoned match doesn't count; its replay is a separate row. A forfeited match counts as a 3-0 win for the other team, whatever score was recorded. - Rank teams by points, then head-to-head points, then goal difference, then goals scored, then team name A to Z. - Head-to-head points = points earned in the matches that count between all the teams level on points (after deductions), with no deductions applied inside it, worked out once for that whole group. Goal difference and goals scored are over the whole season and include forfeits as 3-0. - Report the champion (1st) and the two relegated teams (the bottom two, 2nd-last first). Write `out/standings.json`: `{"table": [<team names, 1st to last>], "points": {"<team>": <points after deductions>}, "goal_difference": {"<team>": <n>}, "champion": "<team>", "relegated": ["<2nd-last>", "<last>"]}`. ## How this run works - Work on your own: nobody will answer questions in this task, and writing to `ask/` counts against the run. - Write only under `out/`. Create `out/` if it is missing. Inputs are synthetic; don't fetch anything from the network. - Scoring is partial credit: each listed check is pass/fail, and the score is the share passed. Numbers are compared to within 0.005 unless the task says otherwise.
