Subject: [PATCH] fix: skip invalid code block metadata without key-value pairs
 (#561)

This ensures compatibility with transformers like `transformerMetaHighlight`, which may include metadata without key-value formatting.

Previously, metadata entries without an = would cause [key, value] to be undefined, potentially introducing invalid entries into the map. We now skip such entries to ensure only valid key-value pairs are parsed.
