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
