shellIntegrationNonce
The nonce to use to verify shell integration sequences are coming from a trusted source. An example impact of UX of this is if the command line is reported with a nonce, it will not need to verify with the user that the command line is correct before rerunning it via the shell integration command decoration.
This should be used if the terminal includes custom shell integration support. It should be set to a random GUID. Inside the Pseudoterminal implementation, this value can be passed through in the relevant sequences to make them trusted.
