v0.9.0 — @dualmark/sveltekit + @dualmark/vercel adapters

The AEO infrastructure your marketing site is missing. This release adds two new edge/framework adapters and improves Astro's config diagnostics.

Highlights

New: SvelteKit adapter — @dualmark/sveltekit@0.9.0

First-class SvelteKit support. Generates .md endpoints from your collections, static pages, and parameterized routes, emits /llms.txt, and ships a createDualmarkHandle() server hook that serves clean markdown to AI bots via content negotiation.

bun add @dualmark/sveltekit @dualmark/core @dualmark/converters

Verified at 125/125 conformance under vite dev. See examples/sveltekit-blog.

New: Vercel Edge adapter — @dualmark/vercel@0.9.0

Drop-in Vercel Edge Middleware that serves pre-built .md twins to AI bots at the edge — wraps any upstream handler with createAEOMiddleware(). Includes subrequest-loop protection, trailing-slash enforcement, Link rel="alternate" injection, redirects, and onAIRequest/onMiss lifecycle hooks.

bun add @dualmark/vercel @dualmark/core

Verified at 120/125 under next dev. See examples/vercel-edge-full.

Improved: Astro config diagnostics — @dualmark/astro@0.9.0

Config validation errors now include the offending file path (e.g. [astro.config.mjs] Dualmark config error: siteUrl is required), so you know exactly which file to fix.
