Changelog

1.0.0

• Added
• Initial release: publisher/author entity settings, per-post schema type meta box (NewsArticle / LiveBlogPosting), JSON-LD injection on `wp_head`, and the `/news-sitemap.xml` Google News sitemap.
• README.md, docs/USER-GUIDE.md, docs/ARCHITECTURE.md, SECURITY.md, and WordPress.org-format readme.txt.
• Security
• Audited the settings `admin-post` handler and the meta box `save_post` handler: both already required the matching capability (`manage_options` / `edit_post`) and verified their nonce inside the handler before touching data; no REST routes, `$wpdb` queries, remote calls, or dynamic code execution exist in the plugin.
• Hardened JSON-LD output: `wp_head` now bails if `wp_json_encode()` fails instead of printing a broken `<script>` tag, and explicitly escapes `</` to `</` as defense-in-depth against a `</script>` breakout if a filter (`newsmark_article_schema_data`, `newsmark_publisher_entity`) alters the encoded string.
