Fix ratio (#162)

* fix: fixed the issue where an error would be reported when only setting the proportioning quantity when creating a proportioning task

* fix: prevent adding the same file multiple times

* fix: implement a more flexible matching strategy, allowing only the tag name to be configured for matching
