I don't know of any language that uses "-" for both negation (prefix,
one operand) and subtraction (infix, two operands) and treats -5
as a single token rather than a unary minus operator applied to the
constant/literal "5".

How about Lisp?  The unary operator is (- 5), the binary (- 10 5).

It doesn't match your second parenthetical remark ("infix") but
otherwise it does.

I know about Lisp.  It doesn't match my description, for the reasons
you pointed out.  It use of -5 as a single token doesn't present the
problems it would in a more C-like language.
