## Description

The Symfony Debug component is a PHP debugging toolkit that converts PHP warnings and notices into exceptions for consistent runtime error handling. It provides a unified error management system by registering a global error handler that intercepts all PHP errors and forwards them to an exception-based pipeline.

The component catches uncaught PHP exceptions and displays detailed stack traces enriched with file, line, and call chain context for developer visibility. It maps PHP error severity levels to corresponding exception types, enabling granular control over how different error conditions are handled during development.

The debugging workflow is integrated through a runtime error-to-exception pipeline that chains error detection, conversion, and exception throwing into a seamless flow. The component also provides an uncaught exception display layer that renders formatted error output for debugging purposes.
