make winopts.fullscreen cover the area of cmdheight?

[aidancz]

As shown in the image, the last line is not covered by the window.

In fact, if zindex >= 200, a floating window can cover the cmdheight area:

vim.api.nvim_open_win(
	0,
	true,
	{
		relative = "editor",
		border = "none",
		row = 0,
		col = 0,
		width = vim.o.columns,
		height = vim.o.lines,
		zindex = 200,
	}
)

Ty @phanen!

Both are the same:

:FzfLua files winopts={fullscreen=true,zindex=200} 
:FZfLua files winopts.fullscreen=true winopts.zindex=200

thank you @phanen!

a small issue: the preview border should be one position right:

Without a border, the preview window seems to be overlapped by the main window.
