Usage:
  orly db health [options]

Options:
  --help, -h    Show this help message

Environment variables:
  ORLY_DATA_DIR          Database data directory
  ORLY_DB_LOG_LEVEL      Logging level

The health check scans the database for integrity issues:
  - Missing serial->eventID mappings (sei)
  - Orphaned serial->eventID mappings
  - Pubkey serial inconsistencies
  - Orphaned index entries

Exit codes:
  0 - Database is healthy (score >= 50)
  1 - Error running health check
  2 - Database has critical issues (score < 50)`)
