shards_list

Constructs a <code>shard_descriptor</code> from a user-supplied list of index vectors.
This is useful for non-contiguous workloads like searchlights/feature sets
where each shard operates on an arbitrary subset.

Provides a parallel execution runtime for R that emphasizes
deterministic memory behavior and efficient handling of large shared inputs.
'shard' enables zero-copy parallel reads via shared/memory-mapped segments,
encourages explicit output buffers to avoid large result aggregation, and
supervises worker processes to mitigate memory drift via controlled recycling.
Diagnostics report peak memory usage, end-of-run memory return, and hidden
copy/materialization events to support reproducible performance benchmarking.
