ProfileIntegrate2D::BoxSum now excludes every predicted reflection's r2 disk
from the r2..r3 background annulus (mirroring BraggIntegrate2D), so a neighbour
Bragg peak can no longer bias a reflection's background high and over-subtract.
With neighbours excluded the annulus can safely widen, so the default r_3 goes
8 -> 10 (more background pixels, lower-variance estimate).
Measured (rotation lyso @1.0 A, external CCref/CCxds vs XDS): 1.05 A CCref +1.3
/ CCxds +1.3, R-meas -5 pts, low-res R-meas unchanged. Serial (Jet8 @0.0002
bandwidth): 1.68 A CC1/2 +3.9 / CCref +1.1, 1.58 A +4.0 / +1.6.
