- Showcase UI Reorganization: * Move web UI dashboard from root directory into apps/showcase_ui/ for cleaner project structure * Add 'artemis ui' CLI command (artemis/interfaces/cli/commands/ui.py) and launcher scripts for the interactive showcase console - Standalone MCP Server & Notifiers (mcp_server/): * Implement dedicated MCP server package with mobile automation tools (device_state, inspect_trace, task_manager, task_runner) * Add multi-channel notifiers (AgentAPI, Desktop notifications, Webhooks, File output, and Composite routing) * Introduce background task runner and trace store for autonomous mobile execution monitoring - Cross-Platform Runtime & Toolchain Support: * Add artemis/platform/ with OS-specific implementations for Linux, macOS (Darwin), and Windows * Add artemis/runtime/supervisor.py for resilient process and agent runtime supervision * Add artemis/toolchain/ with dependency resolution and SDK descriptors * Add cross-platform launcher scripts (start.sh, start.bat) and installer scripts (scripts/install_deps.*) - Core Enhancements & Diagnostics: * Enhance coordinate normalization, OCR API fallback, and perception pipeline * Add credential validation (credentials_validator.py) and system diagnostics * Update bilingual documentation (README.md, README_CN.md) and architecture diagrams - Test Suite Expansion: * Add integration tests for cloud gateway, remote ADB, and Artemis login * Add unit tests covering core diagnostics, platform detection, toolchain, credentials validator, optional OCR, and MCP tools
