feat: improve f-droid link handling
- Handle only app-specific links - Add pathPrefix to handle only app-specific links The pathPattern .*/packages/.*\..* ensures that the path contains /packages/ followed by a string with at least one dot, which is characteristic of a package name. This will correctly handle URLs like https://f-droid.org/en/packages/com.klee.sapio/ and ignore URLs like https://f-droid.org/en/packages/.
