Closes #358

Summary

• create a new justfile recipe that runs tests with ASAN enabled
• add a concurrent CI job that runs ASAN as a required CI step
• pins the MacOS LLVM toolchain instance to the homebrew installation
  • prevents runtime ASAN symbol version mismatches, since the symbols from apple's 1st-party llvm distribution don't match the rust-bundled version.

NOTE: stacked on top of #356, needs to be rebased before merge

Stacked PRs might not work (yet) with forked repositories. Marking this as Draft until #356 has been merged.

[uklotzde]

I tried to merge main. But there are still differences. Please rebase.

A first local test on Linux/Fedora failed.

🟡 Changes recommended

The ASAN CI matrix can test an unintended target, and unpinned LLVM/nightly versions can cause required-job failures.

1 open issue

• Matrix target is not enforced by the ASAN test · New

What changed in this PR

Adds AddressSanitizer test coverage for Rust tests and integrates native Linux/macOS ASAN jobs into CI.

Changes:

• Adds nightly ASAN test recipes with leak detection.
• Adds Linux and macOS ASAN CI matrix jobs.
• Updates the array ownership test to transfer raw allocation ownership safely.

File	Description	Review findings
src/​ua/​array.rs	Updates the raw-array test to use move-based ownership transfer.	No unresolved findings.
.justfile	Defines reusable nightly ASAN test and command recipes.	No unresolved findings.
.github/​workflows/​test.yaml	Adds Linux/macOS ASAN jobs and macOS LLVM configuration.	The matrix target is not enforced by the test recipe; the LLVM/nightly pairing is not pinned or verified; and required-check configuration may still need repository-level updates.

_{Review effort: Lite}

I feel like this is going to be a complete noop practically. If the target triple is set to something else other than the system's target triple, it's either going to run fine (e.g. x86_64-linux-unknown-musl vs -gnu) or it's going to have an incompatible ABI and running it is going to fail
