Publish @signet/sdk v0.1.0 to npm

[blockchain-maxis]

The SDK is workspace-only, so no integrator can install it.

Acceptance: published under a public scope with a README quickstart that runs
against the live API; prepublishOnly runs build + tests; version tagged in git.

Good day maintainer,I would like to apply for this issue. I can configure the package setup to publish @signet/sdk v0.1.0 to npm under a public scope. I will ensure prepublishOnly triggers the build and test suite, add a clear README quickstart targeting the live API, and tag the final release version in git. I am ready to open a clean, high-quality Pull Request today.
