The desktop app can switch Phase 4 steps off and on after a run, lets you pick any frame in the
recent-frames table to view it, and runs Phase 1 faster; the Gaussian blur and bilateral kernels
are quicker too.

Added

• The desktop app can switch the post-processing steps of a finished run off and on. A
  "Post-processing steps" panel under the preview has a box per step the run used (denoisers,
  deconvolution, star reduction, local contrast, final sky flatten and others); ticking or
  clearing one redoes only that step and the ones after it and updates the preview and the
  files the run wrote. On a full Sunflower-size frame a late step takes 3-8 s instead of the
  22 s a whole Phase 4 takes. Background and chroma steps redo the whole of Phase 4. The
  starless sidecar of --remove-stars is not rewritten by a toggle. A "Show without stars"
  box in the same panel previews the image without its stars (the inpaint remover, run on the
  finished image) and saves <stem>_starless.jpg next to the preview; the stars-in files are
  left as they are. Not offered for runs with
  --uncertainty-propagate, --error-aware-stretch, --hdr-combine, --annotate or a
  multi-session combine.

Fixed

• Re-running a session from the _config.toml an --auto run saved now processes the frames
  the same way. --auto asked for per-frame gradient removal on nebulae and galaxies, but it
  decides after the frames are already processed, so the step never ran on the --auto run
  itself; only the saved config switched it on, which made the re-run slower and changed which
  frames passed the quality gates. --auto no longer asks for it.

Changed

• Faster Gaussian blur and bilateral filter (astro_native 0.63.1). The Gaussian blur behind the
  background, sky and star-detection steps now runs tap by tap with a run-time AVX2 path: on a
  2033x3041 frame at sigma 1 / 3 / 8, 24 / 63 / 177 ms became 14 / 18 / 40 ms, with bit-identical
  output. The colour bilateral filter is about 1.5x faster, also bit-identical. The crate's source is
  split into one module per domain; no behaviour changes. Kernel timings only: the effect on a whole
  run was not measured.
• The desktop app's per-frame thumbnail strip is gone; the RECENT FRAMES table does its job. Click a
  row, or step through the rows with the arrow keys, to see that frame in the preview. The frame stays
  up while the run continues; picking a stage from the drop-down goes back to following the run. Every
  processed frame now gets a thumbnail (--ui-frame-every defaults to 1, was 5), made from a copy
  averaged down to thumbnail size first, which costs about a tenth per thumbnail of stretching the full frame
  did. Through the app, Phase 1 of a 158-frame Sunflower session took 44 s, against 64 s before
  (three runs each, alternating, spread under 1 s). A frame rejected before it was rendered
  has no thumbnail and says so. Previously a frame picked from the strip was replaced by the latest
  stage at the next update during a run.
• A mosaic tile much fainter than its neighbours (shot through cloud, haze or dew) is now
  named in a warning. Its brightness cannot be matched to the others, so its outline shows in
  the mosaic; before, that happened without explanation.
