The azimuthal-integration solid-angle correction used cos^3(2*theta), where
2*theta is the true scattering angle (from LabCoord, including detector tilt).
The solid angle of a flat pixel actually depends on the incidence angle to the
detector normal, cos(alpha) = det_distance / |detector-frame position|, which is
invariant under detector tilt (rot1/rot2/rot3). Only for an untilted detector do
the two agree. Switch CalcAzIntSolidAngleCorr(x,y) to the tilt-invariant form,
matching PyFAI solidAngleArray and MAX IV azint. Drop the q-only overload (it can
only ever be the untilted approximation and was used only in tests) and move its
test onto the (x,y) form; add a tilt-invariance test.
XtalOptimizer's residual reconstructed each spot's lab position from rot1/rot2
only, hardcoding rot3 = 0, while the rest of the pipeline (and its own spot
selection) used the full PONI rotation. An imported non-zero rot3 was therefore
silently dropped during refinement. Bake rot3 into the residual as a fixed
Rz(-rot3) so refinement stays consistent (no-op when rot3 == 0).
Polarization and azimuthal binning already honoured rot3 via the full PONI
rotation (Phi_rad), validated against PyFAI chi() by the existing rot3 phi tests.

This is an UNSTABLE release. The release has significant modifications for data processing - in case of troubles go back to 1.0.0-rc.144.
* jfjoch_broker: Improve azimuthal integration (add <I^2> calculation)
* jfjoch_broker: Fixes around indexing, aiming to handle multi-lattice crystals (work in progress, it is not fully integrated)
* jfjoch_writer: Save mean(I), stddev(I), and count(I) for each azimuthal bin

This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132.
* Multiple small bug fixes scattered across the whole code base. (detected with GPT-5.4)
* jfjoch_viewer: Improve image render performance

This is an UNSTABLE release. This version adds scalign and merging. These are experimental at the moment, and should not be used for production analysis.
If things go wrong with analysis, it is better to revert to 1.0.0-rc.124.
* jfjoch_broker: Improve logic on switching on/off spot finding
* jfjoch_broker: Increase maximum spot count for FFBIDX to 65536
* jfjoch_broker: Increase default maximum unit cell for FFT to 500 A (could have performance impact, TBD)
* jfjoch_process: Add scalign and merging functionality - program is experimental at the moment and should not be used for production analysis
* jfjoch_viewer: Display partiality and reciprocal Lorentz-polarization correction for each reflection
* jfjoch_writer: Save more information about each reflection
