Pull Request Overview

This PR enhances exception handling in hostFileNative, adding nested try-catch blocks to map specific C++ exceptions to distinct JNI error codes and reformats the native method signature.

• Wraps file hosting logic in an outer and inner try-catch to handle UnknownFileType, UnsupportedFileType, generic std::exception, and all other exceptions with different error codes.
• Updates engine_priority initialization formatting and adjusts logging calls.
• Reformats method signatures for hostFileNative and listenServerNative.

• [nitpick] The new error code -5 for UnknownFileType should be documented—add a comment or update JNI-side docs to explain this mapping.

• [nitpick] New exception branches (UnknownFileType, UnsupportedFileType, etc.) lack unit or integration tests—add tests to verify each error code path.

        } catch (const odr::UnknownFileType &e) {
