Default Tab mapping is not mapped with lazy loading

[dzirtusss]

Default <Tab> binding is never executed when lazy loading (e.g. with lazy.nvim) because it is triggered by VimEnter event, which, in case of lazy loading, will happen before plugin code is executed.

And when plugin code will be executed, VimEnter will be far gone.

 autocmd VimEnter             * call s:MapTab()

IMO, this needs some other way of triggering.

PS triggering manually later on:

doautocmd <nomodeline> codeium VimEnter

fixes the issue and binds <Tab> properly
