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
