Commit Message

asan: fix internal allocator hardening

Fix several hardening allocator issues:
* guard ASAN redzone/alignment size arithmetic against overflow;
* avoid treating tail munmap addresses as full ASAN mmap allocations;
* route freed blocks through a bounded quarantine instead of leaking all
  allocations forever;
* free old realloc blocks through the same quarantine path.

Add allocator hardening tests for oversized allocation handling and
quarantine release behaviour.
