v0.4.2 — fix: create-ig-harness clones from OSS mirror

Patch release.

Fixed

• create-ig-harness scaffolder failed for external users (#1). The repo URL was hardcoded to Shudesu/ig-harness.git (private), so npx create-ig-harness always errored on git clone with a permission failure. Now points at Shudesu/ig-harness-oss.git.
• package.json repository.url metadata also corrected to the public mirror.

npm

• create-ig-harness@0.4.2 published

Upgrade

```bash
npx create-ig-harness@latest
```
