enhance: various logging and docs fixes

[wass3r]

❤ THANKS FOR HELPING OUT :D

Proposed change

Adds some consistency to the logging. Also, should be able to run mostly with debug: false and get a decent amount of logs.

Also uses non-JSON logging when cli: true is set since it's expected to be used in terminal.

🚨 WARNING: with debug: true it's possible for some sensitive info to show in logs. i've seen the verification token show up (though that's been deprecated and replaced with the signing secret).
