Description

Issue Description:

In non-exec-model,

Where Fact.value1 and value2 are both BigDecimal,

    when
        $fact : Fact( $value1 : value1,
                      $value2 : value2 )
    then
        $value1 = 5;
        $total = $value1 + $value2;

this rule fails with

Exception executing consequence for rule "Rule 1" in com.example.reproducer: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.math.BigDecimal (java.lang.Integer and java.math.BigDecimal are in module java.base of loader 'bootstrap')

$value1 = 5; makes $value1 as Integer type.

exec-model has no issue because `5` is coerced to a BigDecimal.

Acceptance Criteria:

Run without an Exception.
Likely meet with the exec-model behaviour
