Pull Request Overview

This PR implements duplicate marks support for the y-prosemirror synchronization, addressing a compatibility issue with the yjs/y-prosemirror library. The changes introduce a hashing mechanism to handle overlapping marks of the same type with different attributes.

• Adds support for duplicate marks by implementing mark hashing when multiple marks of the same type exist
• Introduces hash stripping functionality to recover original mark types during deserialization
• Updates test suite to include overlapping mark scenarios and improves test infrastructure
