Exercise 1.1.24(a) still quantified over all intervals after teorth#521 fixed add/mono; scalar linearity has the same missing I argument. Co-authored-by: Cursor <cursoragent@cursor.com>

Bug
riemann_integral_smulconcludedriemannIntegral (c • f) = c • riemannIntegral fwith no interval argument, while the hypotheses only constrain behavior onI.Root cause
Same omission as the old
riemann_integral_add/riemann_integral_monostatements fixed in #521.Why this fix is correct
Exercise 1.1.24(a) is linearity on a fixed interval:
riemannIntegral (c • f) I = c • riemannIntegral f I.Test plan
