fix(release): build cli napi artifacts from sdk

[TrueNine]

Summary

• build CLI native npm artifacts from sdk instead of the Rust shell in cli
• unblock build-napi so publish-cli and publish-mcp can run again

Root cause

release-cli.yml tried to run napi build --features napi inside cli/, but tnmsc-cli-shell has no napi feature. The actual NAPI crate is sdk/.

Validation

• local targeted check confirmed the same napi build ... --features napi command succeeds in sdk/
• GitHub Actions on merge will run the real multi-platform release path
