  Copy over CG-CLEAN method from ARDG-LibRA to CASA Method is described in detail in: https://ui.adsabs.harvard.edu/abs/2026A%26A...706A...77M/abstract (Mueller, Genie, Bhatnagar 2026: Accelerating the CLEAN algorithm of radio interferometry with convex optimization) For now, only the CG option is implemented, with momentum acceleration to follow later. Implementation is done by adding a new keyword to tclean (majorcycle) detailing which major loop heuristics is used, i.e. CS (Cotton-Schwab) or CG (conjugate gradients) The algorithm and its improvements are tested for continuum, polarization and cube imaging, with a variety of gridders including mosaics,w/a/aw-projection, TBD: validation for mvc A shallow set of examples to reproduce the improvements is linked to the Jira ticket

CAS-14719: guard against division by zero in getCommonBeam ellipse transform
_transformEllipseByScaling divides by 2*j1-1 = |u|/sqrt(f1), which is
exactly zero when the scaled ellipse is circular (u = r - t = 0). That
is an ordinary geometry, not a degenerate input, but the resulting
0/0 evaluates to NaN; the enclosing GaussianBeam then fails
setMajorMinor, and the exception propagates as a failed minor cycle
in automasking. Reproduced on a 6-channel block whose beams share a
single float32 minor axis and whose position angles differ by ~1e-8
rad, so r and t land on the same double.

Take the analytic limit (k = (r+t)/2 +- sqrt(s)) instead of dividing,
and stop the enclosing-beam retry loop from rebuilding a non-finite
beam inside its own catch handler. Also correct the circle branch,
which returned sqrt(k) where the semi-axis is sqrt(1/k); it was
unreachable before and is reachable now.

CAS-14719: avoid small ragged trailing block in cube minor cycle partitioning
numblockchans derived blksize from nproc and then took nblk=nchan/blksize,
truncating the division; the remainder was re-appended as an extra, much
smaller trailing block. nblk was routinely nproc+1 and the orphan block
could hold only a few channels. The deconvolver derives its mask-smoothing
beam from the block's own beam subset, where getCommonBeam returns
trivially for a single-beam set but enters ill-conditioned arithmetic for
a few very similar channels. Decide the block count first, rounding up so
no block exceeds optchan, then split the channels evenly.
