+- **Dropped Docusaurus Support**: Upgraded the pinned Zenzic Core to `v0.12.0`, which surgically eradicates the Docusaurus adapter due to ontological incompatibility (React-injected IDs and MDX partial merging). Projects still relying on Docusaurus MUST remain on the `v1` floating tag (`v1.3.x`).
+- **Major Version Bump**: The action major version is bumped to `v2` to prevent breaking existing Docusaurus consumers tracking `v1`.
