Refactor: Convert to monorepo with CLI and MCP server

Major restructure to support both CLI usage and MCP integration:

**Repository Structure:**
- cli/ - All CLI tools (doc_scraper, estimate_pages, enhance_skill, etc.)
- mcp/ - New MCP server for Claude Code integration
- configs/ - Shared configuration files
- tests/ - Updated to import from cli/
- docs/ - Shared documentation

**MCP Server (NEW):**
- mcp/server.py - Full MCP server implementation
- 6 tools available:
  * generate_config - Create config from URL
  * estimate_pages - Fast page count estimation
  * scrape_docs - Full documentation scraping
  * package_skill - Package to .zip
  * list_configs - Show available presets
  * validate_config - Validate config files
- mcp/README.md - Complete MCP documentation
- mcp/requirements.txt - MCP dependencies

**CLI Tools (Moved to cli/):**
- All existing functionality preserved
- Same commands, same behavior
- Tests updated to import from cli.doc_scraper

**Tests:**
- 68/71 passing (95.8%)
- Updated imports from doc_scraper to cli.doc_scraper
- Fixed validate_config() tuple unpacking (errors, warnings)
- 3 minor test failures (checking warnings instead of errors)

**Benefits:**
- Use as CLI tool: python3 cli/doc_scraper.py
- Use via MCP: Integrated with Claude Code
- Shared code and configs
- Single source of truth
