leonarski_f	b9f8c2b675	reader/viewer: snapshot image->original map; subset runs register and overlay ... Foundation for a dataset (snapshot or, later, the main file) being a subset of the truly collected images: - JFJochReaderDataset gains source_image_number (image index -> original image number; empty = identity). - HDF5MetadataSource reads /entry/detector/number into that map and an inverse (original -> local) map; FillPerImage / ReadSpots translate the requested global image to this source's local index via ToLocalIndex (return nothing if the image is not covered), so partial snapshots are correct and never read out of bounds. - RegisterSnapshot now accepts a snapshot with fewer images than the dataset (only rejects more), so sub-range / strided reprocessing runs register. - The dataset-info plot draws each run at its original image numbers (x map from source_image_number), so a subset run lands at the right place on the shared axis. The live run's map is filled from msg.original_number. This makes the foundation ready for strided / filtered selections (e.g. reprocess only images with >N spots) without restricting to a min-max sub-range.

leonarski_f	9434878c92	reader: split metadata reading into HDF5MetadataSource + snapshot map ... Complete the image/metadata decoupling. JFJochHDF5Reader is now a thin JFJochReader facade composing one shared HDF5ImageSource (raw pixels) with a name->HDF5MetadataSource map and an active selection ("snapshots"). - HDF5MetadataSource owns one master file: dataset-level parse (Open, ex-ReadFile), per-image metadata (FillPerImage, ex-LoadImage_i), ReadSpots/ReadReflections/ ReadCalibration, and the master-first helpers. It locates per-image metadata either via the shared image source (original file: metadata co-located with pixels) or in its own master at the global index (integrated _process.h5 snapshot) - so switching snapshots never reloads pixels. - Facade adds RegisterSnapshot/SetActiveSnapshot/SnapshotNames/ActiveSnapshot; ReadFile registers the original as "Original". All existing JFJochReader callers are unchanged. - The global hdf5_mutex is taken once in the facade; the sources assume it is held. Adds JFJochReader_Snapshots test (original _master.h5 + a reprocessing _process.h5 over the same images: pixels stay from the original, metadata follows the active snapshot). Verified: tests/jfjoch_test [HDF5] (80 cases / 1810 assertions), plus jfjoch_process/ azint/extract_hkl/scale and jfjoch_viewer all build against the refactored reader.
