post command notices fail to print on some commands

### Description

For example, turning on telemetry audit and running invoke with the session id doesn't print the log file where telemetry was logged.

### Steps to Reproduce

1. enable telemetry audit.
2. run agentcore invoke (non-TUI).
3. verify that telemetry audit file is not logged.

### Expected Behavior

file should be logged.

### Actual Behavior

no file logged.

### CLI Version

### Additional Context

This also affects update notifications, and telemetry notices for first run users.

Likely cause is that we kill the process prematurely.
