Pull Request Overview

This PR refactors the RawBufferSource struct to remove dependency on the ouroboros crate for self-referencing patterns. The refactoring changes how the struct manages its cached string representation of buffer data.

Key changes:

• Removes ouroboros dependency and self-referencing patterns from RawBufferSource
• Replaces borrowed string cache with owned string storage using Option<String>
• Updates all trait implementations to work with direct field access instead of ouroboros methods
