test: enable lambda Node-API examples

[huytdps13400]

Summary

• enable the three upstream Node-API examples that were skipped for lambda support
• add each example to the mobile runtime suite with exact output assertions
• remove the stale lambda TODOs; the current gyp-to-cmake CLI already emits cxx_std_17, so no transformer workaround is needed

This addresses the lambda portion of #423. The independent noexcept and output-directory items remain out of scope.

Verification

• pnpm run build
• pnpm test
• pnpm run lint
• pnpm run prettier:check
• Apple: all three examples compiled into universal iOS Simulator XCFrameworks
• Android: all three examples compiled for arm64-v8a, armeabi-v7a, x86, and x86_64

Note

node-addon-examples verify expects a release-style Apple build containing both the ios-arm64 device slice and the simulator slice. The local current-development build produces only the universal simulator slice, so that verifier stops on the pre-existing async-work example before reaching any newly enabled example. Both native platform builds above complete successfully.
