feat: improve code quality and fix runtime argument passing bugs

- Add PHPStan static analysis and PHP CS Fixer for code quality
- Fix FunctionValue::call method to use proper callable invocation
- Correct ObjectValue built-in functions to accept $args array pattern
- Fix method name inconsistencies (evaluateAsBool → asBool) across RuntimeValue classes
- Add proper type validation and error handling in built-in functions
- Establish consistent argument passing pattern for all RuntimeValue methods
- Add GitHub Actions workflow for automated code quality checks
- Support PHP 8.4 in CI/CD pipeline
