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: Use httplib for HTTP server instead of Pistache
* jfjoch_broker: Drop OpenSSL support
* jfjoch_broker: Base work for multi-lattice support in the future
* Update dependencies to more recent versions (spdlog, HDF5, Catch2, httplib)
Reviewed-on: #41
This is an UNSTABLE release and not recommended for production use (please use rc.111 instead).
* jfjoch_broker: Default spot finding settings can be configured via config JSON
* jfjoch_viewer: FFT analysis of data in the dataset plot
