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.
