Make the analyze process more verbose or add loading in CLI

[CoderMayhem]

When the analyze command is run to generate the threat modeling report right now, it takes some time and the cli remains idle - we can add some verbosity and loading indicators in the CLI to make this look better.

Reproduce :

• extract graph json for an agent app
• run the analyze command on it
• wait for the report to be generated (verbosity/loading to be added here)
