This test validates the core functionality of the arena (bump) allocator in isolation. It verifies:

1. Correct creation and destruction of the arena.
2. That infix_arena_alloc returns non-nullptr pointers for valid requests.
3. That pointers returned by infix_arena_alloc are correctly aligned.
4. That infix_arena_calloc returns zero-initialized memory.
5. That the allocator correctly detects out-of-memory conditions and returns nullptr without crashing when the arena's capacity is exceeded.
