sports schedule data to CloudKit. Includes:

- Multi-source scrapers for NBA, MLB, NFL, NHL, MLS, WNBA, NWSL
- Canonical ID system for teams, stadiums, and games
- Fuzzy matching with manual alias support
- CloudKit uploader with batch operations and deduplication
- Comprehensive test suite with fixtures
- WNBA abbreviation aliases for improved team resolution
- Alias validation script to detect orphan references

All 5 phases of data remediation plan completed:
- Phase 1: Alias fixes (team/stadium alias additions)
- Phase 2: NHL stadium coordinate fixes
- Phase 3: Re-scrape validation
- Phase 4: iOS bundle update
- Phase 5: Code quality improvements (WNBA aliases)
