Title: Deterministic, Zero-Copy Parallel Execution for R
Version: 0.2.0

Description: 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.
