Improve context for errors thrown by compiler
This commit introduces a custom error object to provide additional context for errors throwing during parsing and compiling operations, improving troubleshooting. By integrating error context handling, the error messages become more informative and user-friendly, providing sequence of trace with context to aid in troubleshooting. Changes include: - Introduce custom error object that extends errors with contextual information. This replaces previous usages of `AggregateError` which is not displayed well by browsers when logged. - Improve parsing functions to encapsulate error context with more details. - Increase unit test coverage and refactor the related code to be more testable.
