* Fix next_run_reason

* Lint and format

* i18n

* Rename to setup helper

* rename ErrorType to NormalizedEntryError

* Better setupHelpText i18n (vibe-kanban a8dd795e)

frontend/src/i18n/locales/en/tasks.json setupHelpText currently isn't very informative. We should change it to 
"{agent_name} isn't setup correctly. Click 'Run Setup' to install it and login." or similar.

* Cursor login should be exempt from the 2 execution process limit (vibe-kanban deca56cd)

frontend/src/components/NormalizedConversation/NextActionCard.tsx

Display run setup even if there are more than 2 execution processes

* Move agent setup to server
