Allow safe integer numbers as int64 and uint64 arguments alongside
bigint values. Reject negative numbers for uint64 and numbers outside
the safe integer range. Keep 64-bit return values as bigint.
Apply validation and conversion across the Fast API, shared-buffer,
and generic argument conversion paths.
Add coverage for Number and BigInt boundaries, invalid inputs, and
single-argument calls before and after optimization.
