v0.2.1: tar.xz Linux target for distros without libfuse2 (#9)

AppImage needs libfuse2 at runtime. Ubuntu/Debian ship it; Arch-based
distros (CachyOS, Manjaro, EndeavourOS) ship fuse3 by default and need
the user to `pacman -S fuse2` first — a first-run friction we don't want.

Adds `target: tar.xz` alongside AppImage/deb. User extracts the tarball
and runs `./skiller` directly — no FUSE, no package manager, no
sudo. Loses menu integration vs AppImage, but that's an acceptable
fallback for the slice of users who get bitten by the FUSE2 dep.

CI workflow glob picks up `*.tar.xz` alongside the other artifacts.
README's Linux row lists all three formats with a one-line picker.

Version bump to 0.2.1 so existing 0.2.0 users can exercise the
electron-updater flow end-to-end (first upgrade from a packaged
Electron release — good smoke test).
