feat: Add NFPM packaging and defer Playwright installation

This commit introduces NFPM configuration in `.goreleaser.yaml` to
generate native packages for various Linux distributions (e.g., .deb,
.rpm, .apk). This provides a more streamlined installation experience
for Linux users.

The Playwright browser installation logic has been moved from `main.go`
to the `Run` function of the `download` command. This change ensures
that Playwright binaries are only downloaded and installed when the
`download` command is actually invoked, improving initial application
startup performance and reducing unnecessary overhead for other commands.

The Goreleaser configuration has also been updated to version 2 syntax
and the `arm` architecture has been removed from builds.
