Better experience when using codecompanion chat as a single buffer in a window

[impankratov]

When working in a tiling window manager, sometimes you have lot's of windows open, so every space counts.
So quite often I find myself opening codecompanion chat buffer and then closing other buffers.

But the issue is that if there's multiple chats open - i can't switch between them if codecompanion buffer is the only buffer in a window:

E5108: Lua: [string "vim/_core/editor"]:355: nvim_exec2(), line 1: Vim(hide):E444: Cannot close last window
stack traceback:
	[C]: in function 'nvim_exec2'

@olimorris wondering if this can be improved somehow. Would it align with your vision of this plugin if i contribute some fix/improvement related to that use case?

Could you share a video showing exactly what you mean. If it's reasonable and something others are likely to experience then absolutely I'll support a PR

@olimorris I think i might be able to better explain the use case in simple steps:

• open nvim, open file (A). So there is 1 buffer opened.
• open codecompation chat. It opens new split buffer, so there are 2 buffers: codecompanion (B) & file buffer (A).
• open another codecompanion chat (for some other task). Codecompanion will switch buffer B with new buffer for second chat.
• let's say that at this moment i'm not interested in buffer A and whant to fully focus on the chat. So while codecompanion's buffer is focused, I press CTRL-W_o to keep only codecompanion buffer B visible.
• after some time, i need to switch back to the first codecompanion chat. If i use the codecompanion mappings to do that - i get an error, because the only buffer in window is codecompanion buffer. And i assume that under the hood, codecompanion switches chats just by closing the buffer and re-opening it again with required chat, thus causing the error. So in order for chat switching to work i have to open some other buffer in split mode, so window will have 2 buffers opened (codecompanion and file buffer)
