OpenCADStudio/plugins#901 - Record the host's rustc --version output in the embedded version_info.json. - Add rustc_version/rustc_declared/rustc_compatible to plugin manifests and release metadata, mirroring the existing acadrust gate. - Reject API v4+ plugins whose declared rustc differs from the host, with a clear one-line error message. - Propagate the rustc gate through the marketplace, install flow, and UI. - Update plugin architecture docs to describe the new ABI metadata.
