Lazy load neo-tree while keeping it hijack netrw

[ofseed]

Quite simple but useful:

vim.api.nvim_create_autocmd("BufEnter", {
  group = vim.api.nvim_create_augroup("load_neo_tree", {}),
  desc = "Loads neo-tree when openning a directory",
  callback = function(args)
    local stats = vim.uv.fs_stat(args.file)
                                                                         
    if not stats or stats.type ~= "directory" then
      return
    end
                                                                         
    require "neo-tree"
                                                                         
    return true
  end,
})

Write this to your lazy.nvim PluginSpec in init field, like

You may think this is not graceful, but in fact, according to netrw's source code, it actually relies on a similar behavior.
