feat(errors): add support for attaching data to errors

[char0n]

Closes #5

[Copilot]

Pull Request Overview

This PR adds support for attaching contextual data to error objects and standardizes error types throughout JSON Pointer handling. It updates error constructors and error throwing in both evaluation and compilation paths while also adding type-checks for inputs.

• Updated error constructors signatures in JSONPointer*Error classes to accept a message and options.
• Revised tests to expect native TypeError for invalid input types.
• Enhanced error context data passed to errors in evaluate and parse functions.
