Major refactor: Consolidate DSS into unified package structure
- Create new dss/ Python package at project root - Move MCP core from tools/dss_mcp/ to dss/mcp/ - Move storage layer from tools/storage/ to dss/storage/ - Move domain logic from dss-mvp1/dss/ to dss/ - Move services from tools/api/services/ to dss/services/ - Move API server to apps/api/ - Move CLI to apps/cli/ - Move Storybook assets to storybook/ - Create unified dss/__init__.py with comprehensive exports - Merge configuration into dss/settings.py (Pydantic-based) - Create pyproject.toml for proper package management - Update startup scripts for new paths - Remove old tools/ and dss-mvp1/ directories Architecture changes: - DSS is now MCP-first with 40+ tools for Claude Code - Clean imports: from dss import Projects, Components, FigmaToolSuite - No more sys.path.insert() hacking - apps/ contains thin application wrappers (API, CLI) - Single unified Python package for all DSS logic 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
