Fixed missing sWAR cap validation in TransactionBuilder.validate_transaction(). The validation calculated projected sWAR but never checked against the team's salary cap. Added: major_league_swar_cap field to RosterValidationResult, validation logic using Team.salary_cap with fallback to config.swar_cap_limit, updated status display with ✅/❌ indicators. Affects both /ilmove and /dropadd commands.
