Compatibility issues with smartparens

[jimeh]

copilot-mode doesn't play nice with smartparens-mode, specifically around {.

When the copilot overlay is visible and next character in the Copilot suggestion is ", manually typing a double quote allows smartparens to insert the matching end character.

However when the next character is {, typing that character seems to prevent smartparens from inserting the matching closing character.

Below is a screen recording of Copilot suggesting both " and {. After typing each character I use C+p to move the cursor up a line to clear the copilot overlay.

You could try to make the function copilot--self-insert do nothing. This was previously used to prevent overlay flickering.
