Closes Shopify/ruby-lsp#2886
We cannot use blanket rescue statements for the entire server because the behaviour for handling errors is different between requests and notifications.
For requests, we want to return
error: message
instead of the typicalyresult: something
. And for notifications, we cannot return anything, we can only log that an error occurred.The approach that I took here is to create handlers that we can use both ourselves and in server add-ons, that provide appropriate error handling for requests or notifications.
I also created convenience methods for returning responses or errors.
