Automatic Account switching when in limit

[fabianthegiant]

We heavily use claude team plan and only have 5h limit. For claude to run indefinitely I want to use 3 Team plans in parallel. For that I've expanded your already existing account switching feature and added limit detaction and automatic switching of accounts. I released it under the branch feat/claude-account-failover. If you think that is usefull please merge that into main would greatly appriciate it!
