fix(check): a Math.* call has the type the emitter gives it

Browse source 
Math.max, Math.sqrt and the rest (and the bare min/max/abs/clamp) are computed inline by the
emitter, and L4 gave each the unknown type, which agrees with everything: Maroon Lake's trail
put Math.max(5, n) into Notify's string field a1 and it failed in LLVM ("%t63 defined with type
i32 but expected ptr"). It was never about two dispatches on a line - one is enough. The checker
now mirrors the emitter: a float/double first argument gives that type (sign an int); otherwise
min/max/abs/clamp keep the first argument's type, sign/floor/ceil/round/posmod/wrap/ping_pong are
ints, the rest fixed. Named arguments or an argument it cannot type leave it unknown.

rejected/math_into_text is the case. Reseeded.
