Detailed Description

Unit tests for AhArenaAllocator.

Tests cover:

• Basic allocation and deallocation
• External buffer vs internal allocation
• LIFO deallocation pattern
• Move semantics
• Typed object allocation
• Alignment
• Query methods (capacity, available, etc.)
• Edge cases (zero allocation, full arena, etc.)
