Crate cjc_runtime 

CJC Runtime System

Provides the core runtime infrastructure for the CJC programming language:

• Buffer<T>: Deterministic memory allocation with COW (Copy-On-Write) semantics
• Tensor: N-dimensional tensor with element-wise ops, matmul, and stable reductions
• ObjectSlab / GcRef: Deterministic RC-backed object slab (replaces mark-sweep GC)
• FrameArena / ArenaStore: Bump-arena per function frame for non-escaping values
• Value: Tagged union for the CJC interpreter
• accumulator: BinnedAccumulator for order-invariant deterministic summation
• dispatch: Hybrid summation strategy dispatch (Kahan vs Binned)
