fix: Exception Handling and multiline comment

[qnixsynapse]

Describe Your Changes

• This pull request addresses two key improvements in the codebase:

  • Exception Handling Improvement:
    Updated the exception handling in the Text struct's ToJson method. The catch clause now correctly captures the exception by reference (const std::exception & e) instead of by value. This change prevents unnecessary copying of the exception object and adheres to best practices for exception handling in C++.
  • Logging Code multiline comment fix:
    Commented out the unused GGUF_LOG macro in gguf_file.cpp using a block comment to resolve compiler complaints about multiline comments.
