Cross-SDK Consistency Review ✅

This PR modifies only java/sdk/src/test/java/com/github/copilot/ffi/NativeRuntimeLoaderTest.java, adding assumeLinuxX64() guards to skip native-runtime extraction tests on non-Linux/x64 platforms.

No cross-SDK consistency issues found. The change is:

• Test-only — no public API surface is modified
• Java-specific by design — NativeRuntimeLoader is a Java FFI concern; other SDKs (Node.js, Python, Go, .NET, Rust) load native binaries through their own platform-specific mechanisms and don't share this code path
• Correctly scoped — the assumption helper is private and self-contained within the test class
