Modules

MessageManagement

• Send messages with embeds, components, reply references
• Edit, delete, bulk delete (2-100 messages)

Moderation (GenServer)

• Event emission for all operations (action log)
• Retry mechanisms for failed operations (3 retries)
• Comprehensive API documentation (moduledocs)
• Usage examples with common scenarios (guide)
• Unit tests for all operations (33 tests)
• Error scenario coverage (not found, empty warnings)
• Rate limit handling tests
• State management tests (warnings, filters, events, reminders)
