• Random selection logic using Math.random() and array manipulation for fair winner selection.
• Database queries to update giveaway records with new winner information and reroll history.
• Enhanced embed creation showing reroll status and newly selected winners.
• Error handling for invalid message IDs, non-existent giveaways, or insufficient participants.
• Permission checking to ensure user authorization for performing giveaway rerolls.
• Winner notification system with automatic mentions and prize distribution information.
• Administrative logging of reroll actions for moderation and audit trail purposes.
• Integration with existing giveaway systems for seamless prize distribution to new winners.
