feat(scripts): rewrite parser as modular Python CLI
Replace monolithic scraping scripts with sportstime_parser package: - Multi-source scrapers with automatic fallback for 7 sports - Canonical ID generation for games, teams, and stadiums - Fuzzy matching with configurable thresholds for name resolution - CloudKit Web Services uploader with JWT auth, diff-based updates - Resumable uploads with checkpoint state persistence - Validation reports with manual review items and suggested matches - Comprehensive test suite (249 tests) CLI: sportstime-parser scrape|validate|upload|status|retry|clear Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
