Implemented RPCs and Their Expected Behavior

AddBook

Adds a new book to the store. If a book with the same ISBN already exists, the operation fails (success = false). Otherwise, the book is added successfully (success = true).

UpdateBook

Updates an existing book in the store based on its ISBN. Returns success = true if the book is updated successfully. Returns success = false if the book with the specified ISBN does not exist.

DeleteBook

Deletes a book from the store based on its ISBN. Returns success = true if the book is deleted successfully. Returns success = false if the book with the specified ISBN does not exist.

GetBooks

Retrieves all books currently stored in the book store. Returns a list of all books.
