Major Changes

• d617dab: feat(sdk)!: CDN document().all() returns index entries, so reading .body no longer compiles

  On the CDN, document(model).all() reads the model's _index, which carries
  frontmatter only — the body lives in the per-slug document and is reachable via
  bySlug(). But all() was typed Promise<T[]>, and the generated document type
  declares body: string. So entry.body type-checked, returned undefined at
  runtime, and pages rendered their headings and dropped their prose — with no
  error, no warning, and a passing typecheck.

  The trap is that the bundled runtime's all() does carry bodies. Code written
  and tested against bundled delivery compiled and passed, then quietly rendered
  empty on CDN. The two modes genuinely differ in shape, so they no longer share
  one return type.

  BREAKING: CdnDocumentQuery.all() now returns DocumentIndexEntry<T>[]
  (Omit<T, 'body'>), and first() returns DocumentIndexEntry<T> | undefined.
  Reading .body off either is now a compile error. Fetch the body with
  bySlug(slug), which returns { frontmatter, body, html }. Runtime behaviour is
  unchanged — this only makes the types tell the truth about what was already
  being returned.

  // before — compiled, rendered nothing
  const sections = await client.document<GuideSections>("guide-sections").all();
  sections.map((s) => renderMarkdown(s.body)); // undefined at runtime
  
  // after — the first line is a compile error; fetch bodies explicitly
  const index = await client.document<GuideSections>("guide-sections").all();
  const full = await Promise.all(index.map((s) => q.bySlug(s.slug)));
  full.map((d) => renderMarkdown(d!.body));
  

  Type-level contracts are now asserted in *.test-d.ts via vitest --typecheck,
  since tsconfig.json only covers src and never type-checked the tests.
