Add computed driving flag to all relationship queries (list_relationships, get_predecessors, get_successors). A relationship is marked as driving when the predecessor's early end date plus lag determines the successor's early start date. Changes: - Add early_start_date and early_end_date columns to activities schema - Parse early dates from TASK table in XER files - Implement is_driving_relationship() helper with 24hr tolerance for calendar gaps - Update all relationship queries to compute and return driving flag - Add contract and unit tests for driving flag functionality - Update spec, contracts, and documentation
