Changes

I have added an 'Unlisted' post feature. Posts marked as unlisted: true are hidden from public listings but remain accessible via a direct URL.

Key exclusions:

• 🏠 Home page list, 📂 Archive page, 🏷️ Tag & Category listings, 📡 RSS feed
• 🔍 Search results (Handled via data-pagefind-ignore in [...slug].astro)

Documentation:

• Updated READMEs in 7 languages (KO, EN, JA, ES, ID, TH, VI, ZH-CN).
• Added Unlisted-Posts-Feature.md for detailed guidance.

How To Test

1. Create a new post with unlisted: true in its frontmatter.
2. Run the site and verify it does not appear on the Home, Archive, or Tag pages.
3. Access the post directly via its URL to ensure it renders correctly.
4. Use the search bar to confirm the unlisted post is not indexed by Pagefind.
5. (Optional) Check the unlisted-sample.md included in this PR.

Screenshots (if applicable)

(If you have a screenshot of a post being hidden or the Pagefind ignore attribute in devtools, please drag and drop it here)

Additional Notes

• pnpm check & format: Both commands were executed.
• Note on existing errors: There are 2 pre-existing type errors in Navbar.astro and archive.astro. These are unrelated to my changes and were present in the base repository. My added logic functions as intended.
• Translations: Multilingual README updates were refined using AI for more natural phrasing.

I noticed that unlisted posts are still appearing in search results. I'm working on a fix and will update the PR shortly.

I've improved the search exclusion logic. If a post is set to unlisted: true, it is now completely excluded from the Pagefind indexing process, ensuring it won't appear in any search results even as a blank entry.
