Add a personalization step to `pyra setup` that asks for the user's name, a one-sentence purpose, and interest areas, then surfaces relevant planned plugins. Store purpose in GeneralConfig and use it in the system prompt so Pyra stays task-focused rather than acting as a generic chatbot. - config/schema.py: add `purpose: str = ""` to GeneralConfig - setup/wizard.py: add _collect_user_profile(), _suggest_plugins(), _USE_CASE_PLUGINS - chat/history.py: replace hardcoded _SYSTEM_BASE with _build_system_base() using config values - config/tui.py: expose purpose field in /config General tab Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
