"""v0.3 PR #9 — User-scope persona/workflow directory tests.

Covers:
1. `ensure_user_dirs_initialized` creates both directories (idempotent).
2. `load_combined_personas` returns seed + user, deduplicated by (name, version).
3. User entries override seed entries with the same key (last-wins).
4. Malformed user persona files are logged + skipped (don't kill the REPL).
5. `load_combined_workflows` mirrors the persona behaviour for workflow YAMLs.
6. Empty user dirs → seed-only.
