- Remove unused config_schema from AgentCatalogItem (schema + route)
- Fix agent_setup system prompt: add extraction agent base behaviour
context so journey LLM knows what is already handled and focuses on
field mappings only; remove redundant data-types question (already
known from user selection); derive data types list dynamically
- Rewrite processing base prompt to use actual tool names
(list_tasks, update_task, add_task_comment, list_notes, update_note,
list_timelines, update_timeline, list_all_projects, create_project)
and enforce update-first strategy before falling back to creation
