feat(meal-planner): structured output for get_meal_plan (v0.10.1)

- Map mplistinterval response to clean JSON list (id, date, type, name,
  recipe_id, can_update, can_delete) — no more raw dump
- SPEC.md: document verified mplistinterval response structure
- Fix two pre-existing ruff SIM warnings (SIM102, SIM105)
