Fix LibraryMode test to expect publish failure without WASM SDK

[Copilot]

Description

The LibraryMode test variant with useWasmSdk: False, isPublish: True is expected to fail, but the test was asserting success for all variants.

Updated test to set ExpectSuccess: false when publishing without WASM SDK, verifying the operation exits with code 1 as expected.

// Publishing without WASM SDK is expected to fail
bool expectSuccess = useWasmSdk || !isPublish;
if (isPublish)
    PublishProject(info, config, new PublishOptions(AssertAppBundle: useWasmSdk, ExpectSuccess: expectSuccess));
else
    BuildProject(info, config, new BuildOptions(AssertAppBundle: useWasmSdk, ExpectSuccess: expectSuccess));

Customer Impact

No customer impact - test-only change.

Regression

No. Test was incomplete, not validating the expected failure scenario.

Testing

Test compiles successfully. The updated test will properly validate all four variants:

• Build without SDK: succeeds
• Build with SDK: succeeds
• Publish with SDK: succeeds
• Publish without SDK: fails (now correctly validated)

Risk

Minimal - test-only change with no production code impact.
