- Implement DevicePool and DeviceExecutionLock concurrency modes (per-device FIFO vs global serialization) - Extend ArtemisClient SDK and CLI with explicit device targeting and concurrency strategy configuration - Add server lifecycle management (artemis restart, stop, status) with cross-platform PID discovery - Update MCP server tools to support multi-device dispatch, trace tagging, and per-device execution - Enhance Showcase UI with step-by-step visual replay, playback speed controls, and device serial badges - Add comprehensive unit test coverage and edge-case verification scripts
