Since github doesn't allow 301 redirects (which isn't surprising), you'll have to make a decision between moving to your new URL structure (and taking a search engine hit) or leaving the URLs the way they are. I suggest you go ahead and make the move. Let the search engine chips fall where they may. If someone hits one of your old links via the search engine, they'll be redirected to the new location. Over time, the search engines will pick up your changes.

Something you can do to help matters is to create a Sitemap where you only list your new pages and not the old ones. This should speed up the replacement of old URLs with the new ones. Additionally, if all your old URLs are in your '/programovani' directory, you can also use a robots.txt file to tell future crawls they should ignore that directory. For example:

User-agent: *
Disallow: /programovani/

It will take a little while for the search engines to catch up with the changes. This isn't really a big deal. As long as the old URLs still exist and redirect actual people to the active pages, you'll be fine.
