Fixes an edge case where a function expression would fail to take a dependency if it referenced a hoisted `const` inferred as a primitive value. We were incorrectly skipping primitve-typed operands when determing scopes for merging in InferReactiveScopeVariables. This was super tricky to debug, for posterity the trick is that Context variables (StoreContext etc) are modeled just like a mutable object, where assignment to the variable is equivalent to `object.value = ...` and reading the variable is equivalent to `object.value` property access. Comparing to an equivalent version of the repro case replaced with an object and property read/writes showed that everything was exactly right, except that InferReactiveScopeVariables wasn't merging the scopes of the function and the context variable, which led me right to the problematic line. Closes #35122
