NUMA CPU/memory pinning is no longer worthwhile: the FPGA DMA buffers are
placed device-local by the kernel (dma_alloc_coherent), the big RAM ring
buffer is random-access (first-touch handles placement), and GPU work is
already spread across all visible devices. So drop the pinning entirely
and with it libnuma.
- Delete NUMAHWPolicy; the only concern worth keeping - GPU selection -
is done directly via pin_gpu() (round-robin over visible GPUs) in the
indexer pool and the Lite analysis threads. CPU-only threads
(FPGA acquire/pedestal/summation/frame-transform) no longer bind
anything.
- Drop get_gpu_numa_node() (sysfs lookup) - only SelectGPUAndItsNUMA
used it.
- numa_policy broker setting is deprecated and ignored (kept in the API
for backward compatibility; warns once on startup).
- Remove NUMA_LIBRARY / numa.h / numaif.h detection from CMake.
- Docs: drop the NUMA dependency, remove the numa_policy config example,
and document running multiple brokers on disjoint GPUs via
CUDA_VISIBLE_DEVICES.
- Remove NUMA_GPU_REVIEW.md (the planning note; this work is now done).

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.

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.124.
* jfjoch_broker: Significant improvements in TCP image socket, as a viable alternative for ZeroMQ sockets (only a single port on broker side, dynamically change number of writers, acknowledgments for written files)
* jfjoch_broker: Delta phi is calculated also for still data in Bragg prediction
* jfjoch_broker: Image pusher statistics are accessible via the REST interface
* jfjoch_writer: Supports TCP image socket and for these auto-forking option
