Deteksi aplikasi terminal (CLI/TUI) + perbaikan shortcut lazydocker

- internal/shortcut/terminal.go: RunsInTerminal() menebak dari library dinamis
  (tanpa lib GUI = aplikasi terminal); script selalu true, .exe wine false
- checkbox 'Run in a terminal window' kini muncul untuk semua executable, bukan
  hanya script, dan terisi otomatis saat berkas dipilih
- dialog edit: kalau entri lama belum menyalakan Terminal padahal aplikasinya
  CLI/TUI, muncul catatan kecil sebagai petunjuk
- tes: script/.exe/binary CLI (test binary)/binary GUI (helium)/lazydocker nyata
- kasus nyata: lazydocker & docker-dash terpasang Terminal=false -> TUI gagal
  ('open /dev/tty: no such device or address'); dengan Terminal=true TUI jalan

 - **Executable shortcut** — picks an ELF/AppImage/script/Windows `.exe`, copies it to
   `~/.local/bin/`, installs the icon, writes the `.desktop` entry.
+- **Terminal apps just work** — CLI/TUI programs (lazydocker, htop, a script) need
+  `Terminal=true`, while GUI apps must not open a terminal. LazyRun guesses this from
+  the libraries the binary links (no GUI library → terminal app), pre-fills the
+  *Run in a terminal window* checkbox, and keeps it editable.
 - **Automatic type label** — every shortcut is tagged with what it actually is,
   detected from the file: `Go`, `AppImage`, `Electron`, `Script`, `Windows`, `Binary`
   (`.exe` files are launched through `wine`), or `PWA` for web apps.
