Add PDC World Darts Championship simulator (128-player bracket) - New DartsSimulator: 128-player single-elimination, 7 rounds with PDC-accurate best-of-sets formats (bo3/bo5/bo5/bo7/bo7/bo11/bo13). ELO_DIVISOR=500 via set-level Bernoulli model. Two simulation paths: Path A (bracket drawn) simulates from actual DB matches; Path B (pre-bracket) seeds top 32 by world ranking in fixed positions and randomly draws the remaining 96 per simulation run (50,000 iterations). - darts_bracket added to simulatorTypeEnum and simulator registry. - world_ranking nullable integer column added to participant_expected_values (migration 0067); batchSaveSourceElos now accepts and persists it. - Admin route /admin/sports-seasons/:id/darts-elo: bulk import with format "Player Name, 2099, 1" (name, Elo, optional world ranking), fuzzy name matching, auto-runs simulation and updates EV/snapshots on save. - DARTS_128 bracket template added (scoring starts at Quarterfinals). - 30 unit tests: math helpers, bracket seeding structure, Path A/B integration. https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz 2026-03-31 18:21:04 +00:00			`ALTER TYPE "public"."simulator_type" ADD VALUE 'darts_bracket';--> statement-breakpoint`
