nvim: Use snacks zen mode

Update to solely use snacks zen mode, removing both twilight and
zen-mode plugins.

For now, we switch to a personal fork of `snacks.nvim` which enables
explicit enabling and disabling of the zen mode.
If it gets upstreamed we can switch back to the regular snacks plugin.

Streamlined some snacks loading and optional lazy-loading.
