Sharper stars in every image from an Origin, and cleaner learned star removal.

Changed

• Sharper stars in every image from an Origin. The learned deconvolver (--deconvolve nn)
  was retrained against Pan-STARRS survey images of the same sky, which are far sharper and
  deeper than any Origin stack. The automatic settings now use it for every target, mixed with
  the learned noise reduction:

  • galaxies: 35% deconvolver, stars about 15% narrower than before, with the same or better
    faint detail and star colour;
  • nebulae, clusters and star fields, which used the learned noise reduction alone until now:
    75% deconvolver, stars 10-35% narrower and 10-20% more faint detail.

  --deconvolve nn on its own uses 75%, and --config nn_deconv_blend=... sets the mix. The
  step takes about twice as long as the noise reduction alone. With the default per-channel
  stretch the sharper star cores render whiter; --stretch-color preserve keeps their colour.

• Three more steps run in the native (Rust) module when it is installed, as in the
  released app: the background's fill under masked regions, the satellite-trail detector's
  Hough transform and the moving-object velocity vote. Results are the same as before.

Fixed

• Learned star removal (--remove-stars-method nn, experimental): no more coloured discs
  and rims where stars were. Bright stars on the Pleiades left blue rings with red-yellow
  centres, and stars near Orion's nebula left red and green discs up to 80 px across. The
  removal now follows each star's own colour from core to halo and fills with plain sky only.
