You can't. But you could make a test table and install the function as
a trigger on that.

Nope. STRICTness is meaningless anyway for a trigger, since it has no
explicit arguments to be strict about. And triggers are always volatile
since the entire point is to have side-effects. In the current code I
am not sure whether it matters if you try to mark a trigger function
stable ... but if the system were actually to enforce the STABLE
restrictions against your function, you'd not like the result. Some day
it probably will enforce them...
