ci: probe glibc linux natives on musl/Alpine#46

Add a non-gating (continue-on-error) musl-probe job for linux-x86_64 and linux-aarch64. The natives are built for the *-linux-gnu ABI, so this checks empirically whether they load on musl rather than guessing. The action steps (checkout, setup-java, Maven fetch, javac) run on the glibc host; only the final `java` runs inside an Alpine/musl JDK container (amazoncorretto:25-alpine), so node-based actions never run under musl. If the probe fails, the fix is to add x86_64-linux-musl / aarch64-linux-musl target triples to build-zstd.sh and ship two more native jars. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Instead of a separate musl-probe job, add the two Alpine/musl legs to the smoke matrix (container + experimental flags). Steps branch on matrix.container: native legs run via JBang on the host; musl legs fetch+compile on the glibc host then run java inside an Alpine/musl JDK container. continue-on-error is per-leg (matrix.experimental), so the six native legs gate and the two musl probes don't.

Adds a non-gating
musl-probejob (linux-x86_64, linux-aarch64) that runs the current glibc native inside an Alpine/musl JDK container — settling empirically whether the*-linux-gnunatives load on musl, instead of guessing.How
Action steps (checkout, setup-java, Maven fetch,
javac) run on the glibc host; only the finaljavaruns inamazoncorretto:25-alpine. This sidesteps the "node-based actions need glibc" problem withcontainer:jobs.continue-on-error: trueso a load failure documents the gap without breaking the workflow.Expected outcome
The native is built for
x86_64-linux-gnu/aarch64-linux-gnu(glibc; no-static), so it likely fails to load on stock Alpine (nolibc.so.6). If so, that's the signal to ship musl natives — a cheap fix: addx86_64-linux-musl/aarch64-linux-musltriples tobuild-zstd.sh.If it unexpectedly passes, even better — glibc natives work on musl and no new artifacts are needed.
Either way the probe turns a guess into a fact. Image is swappable if
