Feature: A configuation setting to hide the files panel by default

[mangelozzi]

I have refered to :h diffview-config-view.x.layout and looked at the config, but there is no setting to disable the file panel by default.

As far as I can see a reasonable way is to create a hook when DiffView opens, and then run:

    hooks = { -- See ':h diffview-config-hooks'
        view_opened = function()
            require("diffview.actions").toggle_files()
        end,
    },

Thanks for sharing the hook solution @mangelozzi. I was wrangling my mind trying to figure a way to do this.

Works great but there is a flicker when start starting diffview now.

I use fugitive.vim because I love tpope's approach to plugin design, very elegant, usually works out of the box in good taste with nothing to remove. I am using jujutsu https://jj-vcs.github.io/, a VCS that can work with a git backend more and more but in jujutsu workspaces (= git worktrees), there is no .git folder and as such fugitive's :Gdiffivew doesn't work which is probably my most used command in nvim.
I initially tried to fork fugitive to add jj support but it's too much vimscript to my taste. I initially looked at Neogit but looks like Neogit supports "Gdiffview" via this plugin.

The workaround works great (I dont see the flicker on my fastest machine, I will try on a slow one) but it would be nice to have it maybe as a DiffviewOpen argument, aka DiffviewOpen --no-file-panel.
