* docs: split v4/v5 content, fix version switcher end-to-end
## Content restructuring
- Split `docs/content/docs/` into `docs/content/docs/v4/` and
`docs/content/docs/v5/` so each version is a fully independent
content tree with no shared-file coupling
- v4 excludes the four pages that are v5-only (AbortController
cancellation docs and the serializable-abort-controller internal page)
- v5 retains all pages; `preRelease` frontmatter field removed (no
longer needed now that each version is its own folder)
- Removed `AbortController` / `AbortSignal` from v4 serialization page
(section moved to v5 only)
## Fumadocs source
- Added `v4docs` and `v5docs` as separate `defineDocs()` collections in
`source.config.ts`; shared `docsSchema` (no more `preRelease` field)
- `source.ts` exports both `source` (v4, `baseUrl: /docs`) and
`v5Source` (v5, same base URL)
## Version routing
- `version-source.ts` simplified: `filterPreReleaseFromNodes` and
`isPreReleaseUrl` logic removed; v4 tree uses `source`, v5 tree uses
`v5Source` + `rewriteNodeUrls`
- v4 `page.tsx`: removed `preRelease` guard (v4Source has no such pages)
- v5 `page.tsx`: uses `v5Source` for `getPage` / `generateStaticParams`
/ `generateMetadata`; `v5Link` wrapper rewrites `/docs/…` hrefs to
`/v5/docs/…` so inline MDX links stay in the v5 context
## Versioned cookbook
- Added `app/[lang]/v5/cookbook/` layout + page (mirrors v4 but uses
`v5Source`, `rewriteCookbookUrlForVersion`, and `V5CookbookLink`)
- `getCookbookTree` accepts a `versionPrefix` parameter; sidebar URLs
are prefixed accordingly (`/v5/cookbook/…`)
- `cookbook-tree.ts`: added `skipVersions?: string[]` per-recipe field
for version-specific exclusions; `distributed-abort-controller` is
marked `skipVersions: ['v5']`
## Version switcher — state & navigation
- New `VersionProvider` context (`hooks/geistdocs/use-version.tsx`)
backed by `localStorage`: URL is source of truth on versioned pages,
`localStorage` carries the preference across non-versioned pages
(cookbook overview, worlds, etc.)
- `VersionSwitcher` uses `useVersion()` context instead of URL-only
detection; now visible on all pages including cookbook
- `DesktopMenu` and `MobileMenu` use `activeVersion` from context so
the "Docs" and "Cookbook" navbar links resolve to the correct version
prefix on every page
- `buildVersionUrl` expanded to handle `/cookbook/…` paths alongside
`/docs/…`; non-versioned routes (worlds, api) return unchanged
- `switchVersion` does a `HEAD` probe before navigating; falls back to
the versioned cookbook or docs home if the target page doesn't exist
in that version (handles v4-only → v5 and v5-only → v4 cases)
## Cookbook content (v5)
- Rewrote `agent-cancellation` recipe using a single `AbortController`
pattern; removed Hard Cancellation vs Stop Signal two-approach
comparison
- Deleted `distributed-abort-controller` recipe from v5 (native
`AbortController` serialization makes it unnecessary)
- Removed references to distributed-abort-controller from
`cookbook/index.mdx` and `common-patterns/timeouts.mdx`

* fix(docs): use abortSignal (not signal) in DurableAgent.stream() options

* fix(docs): update prepack scripts to use versioned content paths
Content moved from docs/content/docs/ to docs/content/docs/v5/ on main
(pre-release channel). Stable branch will use v4/ after backport.
