Obol Agent Init can read from stdin/walk the user through the journey #117
Description
Problem to be solved
You need to craft the right command to pass an api key to obol agent init, you probably don't know that first time around.
Proposed solution
If you run obol agent init without it, you get an await stdin.
For now, it can be a log line like 'go to ai studio, create an api key, paste it here and press enter'.
I believe before long, we'll end up doing an oauth flow in the CLI for someone to log in and give us a token to use. We may cross that bridge when it makes sense.
This stdin should be parsed as an api key and saved as a secret, as per the existing flow.
