fix: handle empty package version in conflict resolution (#346)

- Add check for empty package version in replace logic
- Fix potential issue when replace.packageVersion() is empty
- Improve conflict resolution reliability

When checking if a package can replace a conflicting package,
the code now properly handles cases where the replace version
is empty, preventing potential comparison issues.
