v0.1.2 Feature flags, safety improvements & allocation fast-path optimization

What's Changed

numa-binding feature flag

• Added a numa-binding default feature flag that gates all NUMA-specific syscalls (mbind, sched_setaffinity, topology detection). When disabled (--no-default-features), the allocator operates in single-node mode — useful for non-NUMA systems or cross-platform builds where NUMA APIs are unavailable.

SysBox<T> — safer system-allocator-backed ownership

• Introduced SysBox<T>, a Box<T>-like smart pointer that always routes through the system allocator. This replaces raw NonNull<PerThreadHeap> + manual System.dealloc in thread-local storage with proper RAII ownership. Thread-local cleanup (draining freelists, flushing large object cache) now happens automatically via Drop instead of manual pointer management.

Allocation fast-path optimization

• Reordered the allocation hot path to check the per-thread freelist cache before touching the global heap, avoiding unnecessary heap access on cache hits.

Code organization

• Moved integration tests from src/lib.rs to tests/local_allocator.rs for cleaner separation of library code and tests.

Full Changelog

• Move lib tests to tests dir
• Create sys box to improve safety
• dont call heap before thread cache checks
• Add a numa-binding default feature flag with selective NUMA support

Bug fix release

Fixes

• NUMAlloc brokes on projects with a lot of allocations (unknown linux gnu)
• Trying to allocate more memory than available

What's Changed

• Fix deadlock and infinite recursion when used as #[global_allocator] by @Mnwa in #1
