Add Ghost CMS feature parity: RSS feed, sitemap, robots.txt, post revisions, taxonomy descriptions, members visibility, password-protected posts, code injection

[Copilot]

Penstack was missing several standard blog CMS features present in Ghost. This PR adds the most impactful ones with minimal changes across schema, API routes, and Next.js conventions.

Discovery & SEO

• RSS 2.0 feed (/rss.xml) — top-50 published posts with title, permalink, pubDate, summary, author, category, and tags; 1-hour revalidation
• XML sitemap (/sitemap.xml) — Next.js 14 native sitemap.ts; covers home, /articles, all published posts (via existing generatePostUrl permalink formatter), categories, and tags
• robots.txt (/robots.txt) — Next.js 14 native robots.ts; blocks /dashboard/, /api/, /auth/; references sitemap

Post Revision History

New PostRevisions table snapshots title, content, summary, and revised_by before every PUT update, inside a transaction:

await db.transaction(async (tx) => {
  await tx.insert(postRevisions).values({ post_id: oldPost.id, ... });
  await tx.update(posts).set({ ...body }).where(...);
});

revision_number is DB-level AUTO_INCREMENT to eliminate race conditions on concurrent edits. New GET /api/posts/[slugOrPostId]/revisions returns paginated history (requires posts:edit).

Schema Additions

Table	Change
Posts	visibility enum gains "members" tier (public | members | private); new access_password varchar(255)
Tags	description varchar(500)
Categories	description varchar(500)
PostRevisions	New table

Tag and category POST/PUT routes updated to accept and persist description.

Site Settings

Added codeInjectionHead and codeInjectionFoot to DEFAULT_SETTINGS and SiteSettings type — the root layout can read and render these via dangerouslySetInnerHTML to match Ghost's code injection feature.

Migration Required

npm run db:gen && npm run db:migrate
# or for dev: npm run db:push
