giles b0a4be0f22 Step 8: numeric tower — exact/inexact predicates + truncate/remainder/modulo ...

7 new R7RS primitives on the float-based tower (Number of float unchanged):
- exact? / inexact? — integer detection via Float.is_integer
- exact->inexact / inexact->exact — identity / round-to-integer
- truncate — toward zero (floor for positive, ceil for negative)
- remainder — sign follows dividend (= Float.rem)
- modulo — sign follows divisor

8 new tests (2658/2658 pass). No type system, VM, compiler, or parser changes.
