[bug] wrong install reason

As I was using `alpm.rs` to read the local database, I found a good number of packages appeared as "Explicit" even though they weren't. For example: <img width="664" height="494" alt="Image" src="https://github.com/user-attachments/assets/2ef3c195-1803-4831-aca2-c9d64703772e" /> pacman clearly says that it is a dependency and not explicitly installed but when using `alpm.rs`, it is marked as "Explicit" I made a repro repository here https://github.com/ArjixWasTaken/alpmrs-bug-repro
