Add three core services for draft system with no caching decorators since draft data changes constantly during active drafts: - DraftService: Core draft logic, timer management, pick advancement - DraftPickService: Pick CRUD operations, queries by team/round/availability - DraftListService: Auto-draft queue management with reordering All services follow BaseService pattern with proper error handling and structured logging. Ready for integration with commands and tasks. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
