Suggestion: improve copilot to work with shell

[ghost]

M-x shell or any of the other shells will often have way more than the character limit in the buffer. However, having copilot-mode enabled for the buffer could be very helpful. Is there a way to use a rolling window to limit the number of characters used by copilot-mode when in a shell buffer?

[zerolfx]

The rolling window has already been implemented in copilot.el. However, it may require rework for the compatibility with the LSP protocol, such as textDocument/didChange messages.
