fix: cooking assistant not reliably calling createRecipe tool

The system prompt only said "you can propose creating a recipe with
the tool" as a soft option — models were defaulting to just writing
the recipe out as prose in the reply instead of invoking the tool,
since that's the easier default behavior for a "write me a recipe"
request. Rewrote the instruction as a hard rule: full recipes must
go through createRecipe, plain-text ingredient lists/numbered steps
are disallowed in the reply for that case.
