Enhancement Plan for PHP CRUD API Generator

After reviewing the codebase, I've identified and implemented several key enhancements to improve the API's functionality, security, and usability:

• Add input validation and sanitization for query parameters
• Fix potential SQL injection in filter parameter (duplicate column names)
• Add field selection capability for list endpoint (e.g., fields=id,name,email)
• Improve filter operators (support for >, <, >=, <=, !=, IN, NOT IN, NULL, NOT NULL)
• Add Validator class for centralized input validation
• Add bulk operations (bulk_create, bulk_delete)
• Add Response helper class for standardized responses
• Add count endpoint for analytics
• Create comprehensive enhancement documentation
• Improve documentation with examples of new features
• Add comprehensive tests for new features
• Update README with new capabilities
• Update CHANGELOG with version 1.1.0
