New app submission: Purclean — system cleaner for Fedora Linux

Hi! I’d like to submit my application to Flathub. App ID: com.github.byoval.purclean GitHub repository: GitHub - byoval/purclean · GitHub Purclean is a GNOME/GTK4 application for cleaning disk space on Fedora Linux. It finds and removes old kernels, Flatpak/Snap caches, systemd journal logs, orphaned packages, browser caches, DNF cache, Docker/Podman data, and duplicate files. My GitHub account is too new to create a PR directly in the flathub/flathub repository, so I’m submitting here. The Flatpak manifest is ready and builds successfully from the GitHub release tag v0.1.0. Thank you!
