leonarski_fandClaude Opus 5 5f4343621c Reader: SMV states a saturation value, and a pixel at it is saturated
CCD_IMAGE_SATURATION is in the header of every SMV file the corpus holds, and it
is the value a saturated pixel carries, as the marCCD field is. The reader never
read it, and said in a comment that saturation was "judged on the 16-bit
container alone" - which the line below it made untrue: the pixels are handed out
as 32-bit, so the fallback limit was INT32_MAX and no SMV pixel could ever be
called saturated, whatever the detector did.

The limit is now the header's value, or the container's maximum where a writer
states none - said explicitly rather than left to the fallback, for the reason
above. One of the new open-arm sets carries pixels at exactly 65535.

* Fixed `jfjoch_broker` cancelling every data collection with a CUDA "out of memory" error after long operation: GPU memory no longer leaks with each collection.
* Rugnux scales a rotation sweep until the per-frame scales settle instead of for a fixed three rounds, and says so when they did not - merged intensities, and the space group, resolution cut and frame rejection read off them, change accordingly; `--scaling-iterations` is now the cap on that loop (default 100).
* Rugnux places every frame of a marCCD, SMV or miniCBF series at the spindle angle its own header states, so a series with missing frames, or with angles written modulo 360, is no longer read at the wrong geometry or refused.
* Every rotation run writes two diagnostic files beside its reflections: `<prefix>_detector.jpg`, the detector projection with the pixel mask and the detected beam-stop shadow drawn on it, and `<prefix>_plot.txt`, one row per image.

* Rugnux: basic support for CCD images (marCCD, SMV) and for gzipped miniCBF.
* `jfjoch_viewer`: opens the CCD formats, and fixes to the dataset plots.
* Documentation updates.
