Bump Astro 5→6, Tina canary→stable, CF adapter 12→13

[0xharkirat]

Why

Sync SSW.Website.Global with the floor of tinacms/tina-astro-starter's main, and move off the date-pinned canary Tina builds onto stable releases.

Also supersedes the open Dependabot PR #23 (covers everything that PR bumps, plus the two it skipped — @tinacms/astro and @astrojs/mdx).

Dependency bumps

Package	From	To
astro	^5.16.0	^6.3.7
@astrojs/cloudflare	^12.6.13	^13.1.10
@astrojs/mdx	^4.3.0	^5.0.6
@astrojs/rss	^4.0.15	^4.0.18
@astrojs/sitemap	^3.7.0	^3.7.2
@tinacms/astro	canary	^0.4.0 stable
@tinacms/cli	canary	^2.4.0 stable
tinacms	canary	^3.8.2 stable
wrangler	4.59.2	^4.95.0
@types/node	^25.1.0	^25.9.1

Other package.json

• Add engines.node: ">=22.12.0"
• Replace pnpm.overrides react pin with explicit react/react-dom devDeps at 18.3.1 (upstream PR fix: restore /privacy page (PR #30 commit was stranded on a merged branch) #45 pattern)

Config

• wrangler.toml — main = "@astrojs/cloudflare/entrypoints/server". Required by the new @cloudflare/vite-plugin in @astrojs/cloudflare v13.
• astro.config.mjs — drop the rollupOptions.onwarn shim; @tinacms/astro@0.4.0 no longer triggers the warning.
• src/content.config.ts (new) — declare the config collection so Astro 6 doesn't glob the JSON-only dir as Markdown. Mirrors upstream.
• src/pages/rss.xml.js → rss.xml.ts — switch to listBlogs() (Tina). Fixes "collection blog does not exist or is empty" under Astro 6.
• public/admin/.gitignore — auto-rewritten by Tina CLI 2.4.

Verification

pnpm run build:local succeeds. Remaining cosmetic warnings: unenv fs.mkdirSync and /home/index.html empty body (redirect ships via dist/_redirects).

Test plan

• pr-lint-code passes (once Add CI, repo policies & lint foundation (closes #6) #18 lands)
• pr-build passes
• CF Workers Builds deploys preview
• /admin/ works, /blog/, /rss.xml render

Skipped

Upstream UI overhaul (blocks/ui/space components, ThemeToggle, Tailwind 4), Vercel adapter, Astro Icon, upstream blog seed, block-builder rewrites of home.mdx / page.ts.

This PR updates the project’s Astro/Tina/Cloudflare toolchain to newer stable versions (Astro 6, Tina stable releases, Cloudflare adapter v13 / Wrangler updates) and applies the related configuration adjustments needed for the upgrade.

Changes:

• Bump core dependencies: astro 5→6, @astrojs/cloudflare 12→13, Tina canary→stable, wrangler 4.59→4.95, plus related integration updates.
• Update Cloudflare Worker entrypoint (wrangler.toml) and simplify Astro build config (remove Rollup warning shim).
• Add Astro content config to avoid JSON-only collection warnings and migrate RSS implementation to use Tina-backed listBlogs().

Independent Codex review (cross-model) + triage

Verdict: merge-able. The Astro 5→6 / Cloudflare adapter 12→13 / Tina canary→stable migration checks out end to end:

• Versions resolve cleanly — astro 6.4.2, @astrojs/mdx@5 (peer astro ^6 satisfied), @astrojs/cloudflare@13.6 (peers satisfied), tinacms 3.8.3.
• wrangler.toml main = "@astrojs/cloudflare/entrypoints/server" is the correct entrypoint for the v13 @cloudflare/vite-plugin model.
• output: 'static' is valid in v13 (static + one on-demand island route is supported).
• No removed Astro 6 APIs left dangling — the old getCollection('blog') RSS path was correctly switched to Tina's listBlogs(), and the dead onwarn rollup shim was cleaned up.

One real fix applied (e0e0c09): the RSS feed linked posts by _sys.filename while the blog routes derive the slug from _sys.relativePath, so a post in a nested Tina folder would 404 from the feed (latent — current posts are flat). Now consistent.

Copilot threads addressed: the site fallback was fixed; the content.config.ts landing suggestion was verified unnecessary (Astro 5+ doesn't auto-glob undefined src/content/ dirs — build:local shows no warning).

Reviewed by Codex (gpt-5.5) + triage verification. No critical or important issues outstanding.
