refactor(logging): streamline OpenGL logging mechanism

- Replaced direct file operations with a static file pointer for logging in `R_ResolveSymbols` to improve performance and reduce file access overhead.
- Updated logging format to include session and run IDs for better traceability.
- Removed redundant log entries from the debug log to maintain clarity and focus on relevant information.
