Fixes the in-app update on Linux package installs. Reported on CachyOS:

The update downloaded but couldn't be installed … Permission denied (os error 13) at path "/usr/bin/tauri_current_app50G5aG"

Tauri's Linux updater can only replace an AppImage. For a copy installed from the Arch package (or the .deb), it tries to write next to the binary in /usr/bin.

Changes

New command update_install_kind:
- in-app on Windows, and for an AppImage ($APPIMAGE set);
- pacman when /etc/os-release ID/ID_LIKE includes arch (Arch, CachyOS, Manjaro, EndeavourOS…);
- deb for Debian, Ubuntu and derivatives;
- manual otherwise.
install_update refuses up front on package installs (install: package-managed (…)), so it doesn't download the whole update first.
Web client: LotusGuild/cinny linux-package-updates PR, which shows the package-manager command instead.

Tested

Unit: CachyOS/Arch → pacman; Ubuntu/Debian/Mint → deb; Fedora/unknown → manual; AppImage and Windows → in-app.
Real Linux release build (Debian container, not an AppImage): update_install_kind → deb; install_update → install: package-managed (deb): … with no download.
Windows: type-checked; install_kind returns in-app there, so the Windows update path is unchanged.

fix(updater): package installs update through their package manager 261d7852cb

On CachyOS the in-app update failed with "Permission denied (os error 13)
at path /usr/bin/tauri_current_app…": the app was installed from the
Arch package, and Tauri's Linux updater can only replace an AppImage — for
anything else it tries to write next to the binary in /usr/bin.

- update_install_kind command: "in-app" on Windows and for an AppImage
  ($APPIMAGE set); on Linux package installs "pacman" (ID/ID_LIKE arch:
  Arch, CachyOS, Manjaro, EndeavourOS…), "deb" (debian/ubuntu and
  derivatives) or "manual". The web UI shows the matching update command.
- install_update refuses up front on a package install
  ("install: package-managed (…)") instead of downloading the whole
  update and failing at the last step.

Tests: CachyOS/Arch → pacman; Ubuntu/Debian/Mint → deb; Fedora/unknown →
manual; AppImage and Windows → in-app.
