Detailed Description

Process-lifetime arena used by level-2 compact-pointer builds.

Mutating operations (reserve, bump allocation, foreign raw-pointer import) are serialized by ThreadSafe / SafelyAccess. Arena-backed handle resolution is intentionally a racey read: an arena handle is a shifted word offset and resolves as base + ((handle - 1) << WordShift). Existing non-arena raw pointers use a high-bit foreign handle stored in an Arrangement<const void*> so the tree can be migrated incrementally without returning to std container side tables.
