feat: wire DeleteVariable to OperatorRegistry as 'd' operator
The 'd' token was previously a no-op error. Now it pops a value from
the stack and deletes the variable with that name.
Accepts Symbol (:x) or StringNum as the variable name. Added
DeleteVariable to VariableOperator interface so the operator can
call it through the Operator interface.
Example: x 5 = :x d vars → No variables defined
