feat(meal-planner): add add_meal_note tool (v0.11.5)

New write tool using mpmealput endpoint to create meal/ note entries
with optional free-text and serving count. Response structure verified
from JS-bundle (Sg class); a00.r.r is a plain object (unlike mpcreate).
Structured output matches get_meal_plan meal entry format.
