Sanitize file title before setting it as the filename

[hemant6488]

I recently ran into an error where the infer title function resulted in the following filename (ls -al output):

-rw-r--r--@  1 user  group   3.7K Jul 29 12:27 Code Explanation Undefined Values in Output??Assistant Response Undefined values in the output.md

The ?? is probably some special characters that the shell couldn't render.
This filename breaks the remotely-save automation with a 400 bad request error.
