Auto update: cek rilis GitHub, notifikasi, dan pemasangan AppImage

- Paket internal/update: ambil rilis terbaru (API GitHub), bandingkan versi semver sederhana, unduh AppImage ke berkas sementara lalu tukar atomik (verifikasi magic ELF+AI; kalau gagal, AppImage lama tetap utuh) - UI: cek otomatis 2 detik setelah aplikasi tampil (hanya kalau jalan sebagai AppImage), dialog notifikasi versi baru + catatan rilis, tombol Update now / Halaman rilis / Nanti - Pemasangan: lewat AppImageUpdate kalau terpasang, kalau tidak unduh sendiri; setelah selesai ditawarkan Restart (jalankan AppImage baru lalu tutup yang lama) - Tombol footer Cek Update memakai alur yang sama dan selalu memberi jawaban - LAZYRUN_UPDATE_API untuk mengarahkan cek update ke server lain (tes/fork) - Tes: perbandingan versi, parsing rilis, penukaran AppImage, penolakan berkas bukan AppImage
