test: add tests for setup wizard personalization and system prompt builder

Cover _USE_CASE_PLUGINS mapping, _suggest_plugins side effects, _build_system_base
output for all name/purpose combinations, and GeneralConfig.purpose round-trip.
Also update CLAUDE.md with the testing workflow rule.

 ## Workflow Rules
 
+### Testing
+
+- **Write tests for every new feature.** A feature without tests is incomplete — do not commit without them.
+- New tests go in `tests/unit/` for pure-logic helpers and `tests/security/` for security-boundary code.
+- All existing tests must continue to pass — run `pytest tests/ -v` before committing.
+- Test pure functions directly; do not test interactive I/O (questionary, Rich output) — only test the logic helpers those flows call.
+- For Rich output, capture side effects by monkeypatching `console.print` rather than using `capsys`.
+
 ### Bugfixes
 
 - **Stay under 50 lines changed.** Find the root cause and fix it directly.
