fix: exit with nonzero code on init cmd error (near#8334)

near#5967 refactored things so that the init command wouldn't panic on normal/expected errors, but it inadvertenly changed things so that we always get exit code 0 even when the command fails, which is quite sad. So just return an `anyhow::Error` from `InitCmd::run()`
