Add worldcup.meta.json per year with host, teams_count, winner, runner_up, third_place, fourth_place — derived from match results (Final/Third-place match) with infobox as fallback for edge cases like 1950's round-robin final. Fix infobox host extraction to handle <br>-separated multi-host entries (2002: Japan / South Korea). Fix squad scraper to filter out zero-player phantom sections that Wikipedia appends (References, Captains, etc.). Drop app/data/world_cup.csv and the PLACEMENTS/parseCsv code in seed.ts — all tournament metadata now comes from the scraped JSON files. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
