Adds Java native runtime packaging, testing, and publishing support for linuxmusl-arm64, matching the existing native classifier pipeline.

  • Packaging

    • Add ARM64 musl Maven profiles for the runtime and SDK modules.
    • Validate ARM64 ELF architecture and musl loader.
    • Attach externally built linuxmusl-arm64 artifacts during publication.

  • CI and publishing

    • Exercise in-process mode on ARM64 Alpine.
    • Build and validate classifier JARs on ubuntu-24.04-arm.
    • Include the classifier in snapshot, release, and local publication assembly.

  • Coverage and documentation

    • Extend native host, artifact, and publication tests.
    • Document linuxmusl-arm64 as a supported in-process platform.

SDK Consistency Review

This PR exclusively adds a new Java-only native-artifact classifier, linuxmusl-arm64, to the existing platform matrix (linux-x64, linux-arm64, linuxmusl-x64, win32-x64, win32-arm64, darwin-x64, darwin-arm64). Changes are confined to:

  • java/copilot-native/pom.xml and java/sdk/pom.xml (new Maven profile + validation/attach wiring)
  • java/copilot-native/scripts/*.mjs (+tests) for host/classifier validation
  • .github/workflows/java-*.yml (build/publish jobs for the new classifier)
  • java/README.md and java/docs/adr/adr-007-native-bundling-strategy.md (docs)

No public API surface is touched — no new client methods, types, or options are introduced in any language. This is purely build/packaging infrastructure specific to how the Java SDK bundles the native Copilot CLI runtime via JNA (per ADR-007), a mechanism that doesn't have an equivalent in the Node.js, Python, Go, .NET, or Rust SDKs (they don't ship native binary classifiers this way).

Conclusion: No cross-SDK consistency issues. This is an appropriate Java-specific platform-support expansion and doesn't require changes in other language SDKs.
