Add an optional Smargon static positioner (chi/phi angles + rotation axes)
that is reconstructed into the NXmx sample transformation chain. Chi/phi are
appended at the innermost end of the chain (closest to the sample) for both
the goniometer and grid-scan branches, with axes defaulting to chi {0,0,1}
and phi = omega default {1,0,0}.
- SmargonPosition gains chi_axis/phi_axis (common/JFJochMessages.h)
- OpenAPI: optional phi_axis/chi_axis arrays; clients regenerated
- OpenAPIConvert wires Dataset_settings.smargon -> DatasetSettings
- CBOR serializer/deserializer round-trip the axes
- tests: CBORSerialize_Start_Smargon

New CompressionAlgorithm that emits a standard Zstandard frame: zero/0xFF runs
become RLE_Blocks (like BSHUF_ZSTD_RLE) and literal regions become
Compressed_Blocks with per-block adaptive Huffman literals and no sequences
(Number_of_Sequences=0). Short runs are absorbed into the literal stream;
incompressible literals fall back to Raw_Blocks so the worst case stays within
ZSTD_compressBound.
The Huffman tree + bitstream are produced by zstd's own HUF_compress{1,4}X_repeat
(the same calls ZSTD_compressLiterals uses); only the frame/block/literals-section
framing is hand-written, with comments citing zstd_compression_format.md so it can
be checked clause by clause. Output decodes with stock ZSTD_decompress, so no
reader changes are needed (decode routes like BSHUF_ZSTD).
On sparse diffraction this gives ~12% smaller files than bitshuffle/LZ4 at about
the same end-to-end speed, sitting between LZ4 and full ZSTD; for maximum ratio
use BSHUF_ZSTD. Robust on any input: tests round-trip pure zeros, Poisson(10),
Mersenne-Twister noise (checked against the size bound), an extreme-sparsity mask,
and a real lyso image through stock ZSTD_decompress.
API: exposed as "bszstd_rlehuf"; regenerate the Python/TS clients (update_version.sh)
to surface the new value there.

This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use.
* jfjoch_broker: Add EXPERIMENTAL pixelrefine mode for image processing
* jfjoch_broker: Allow to load user mask from 8-bit and 16-bit TIFF files
* jfjoch_broker: Add ROI calculation in non-FPGA workflow
* jfjoch_broker: Fixes to TCP image pusher
* jfjoch_broker: Remove NUMA bindings
* jfjoch_broker: Improvements to indexing
* jfjoch_broker: For PSI EIGER, trimming energies are taken from the detector configuration (now compulsory) instead of hardcoded values
* jfjoch_writer: Save ROI definitions and the per-pixel ROI bitmap in the master file; azimuthal ROIs support phi (angular) sectors
* jfjoch_viewer: Major redesign with dockable panels and saved layouts, plus on-canvas creation/move/resize of box, circle and azimuthal ROIs
* jfjoch_viewer: Run jfjoch_process reprocessing jobs from inside the GUI and overlay per-run results

This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132.
* jfjoch_broker: Further reduce startup time for DECTRIS detectors by selectively modifying SIMPLON parameters on `/start`
* jfjoch_broker: Further reduce startup time for DECTRIS detectors by not setting beam center and detector distance via SIMPLON API on '/start'
* jfjoch_broker: Add an extra message to ZeroMQ puller ready to monitor Lite worklow preparation time
* jfjoch_broker: Image buffer configuration is postponed for Lite receiver flow till start message is received
* jfjoch_broker: Use nanoseconds internally for frame/image/readout time
* jfjoch_broker: Extra messages added for receiver operation (to be removed after debugging finished)
* jfojch_broker: Improve profiling of different data analysis steps
* jfjoch_broker: Record integration reflection count
* jfjoch_broker: Fix bug where ZeroMQ preview frequency was confusing time units (micro vs. milliseconds)
* jfjoch_broker: Fix bug where '/wait_till_done' got deadlocked
* jfjoch_writer: Fix confusion between NaN and zero in floating-point datasets
**Breaking changes**: detector definition is now using nanoseconds to define minimum frame time, minimum count time and readout time.

* Multiple small bug fixes scattered across the whole code base. (detected with GPT-5.4)
* jfjoch_viewer: Improve image render performance
