feat: implement comprehensive GraphQL read interface (issue #9)
Adds a complete GraphQL API for querying MarkiTect database content including: CORE FEATURES: - Type-safe GraphQL schema with comprehensive field definitions - Full database access: markdown files, schemas, ASTs, and metadata - Advanced search capabilities with relevance scoring - Pagination support for efficient data access - Real-time schema introspection and development tools IMPLEMENTATION: - GraphQL schema definition with 6 core types (MarkdownFile, Schema, AST, etc.) - Complete resolver implementation with database integration - Flask-based GraphQL server with CORS support - GraphQL Playground for interactive development - Health check and schema introspection endpoints CLI INTEGRATION: - graphql-serve: Start GraphQL server with customizable options - graphql-query: Execute queries from command line (local/remote) - graphql-schema: Retrieve schema definition in SDL/JSON format - graphql-examples: Comprehensive usage examples and documentation API FEATURES: - Single item queries (by ID or filename) - List queries with filtering and pagination - Full-text search across files and schemas - Database statistics and analytics - AST querying with JSONPath expressions - Computed fields (word count, line count, etc.) TESTING: - Comprehensive test suite with 38 passing tests - Unit tests for schema, resolvers, server, and client - Integration tests for query execution - Error handling and edge case coverage - Mock and fixture support for isolated testing DOCUMENTATION: - Complete API documentation with examples - Usage guide for all CLI commands - Programming examples in Python and JavaScript - Performance optimization guidelines - Troubleshooting and security considerations The GraphQL interface enables developers to build rich applications on top of MarkiTect data with flexible, efficient querying capabilities. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
