Pull Request Overview
This PR adds error handling to prevent LSP handlers from processing requests when the server hasn't been properly initialized. It addresses debugging issues like #1744 by returning proper error messages when clients attempt to use the language server before the initialization handshake is complete.
- Adds initialization checks to both notification and request handlers
- Returns
ErrServerNotInitializedwhen session is nil and method is not an initialization method
