- Global installs: `devtoolsGlobal`, the `-g` install flag and `NuxtDevtoolsInfo.isGlobalInstall`.
- The `viteDevTools` module option; Vite DevTools is always on. On Vite 8.3+ Nuxt DevTools configures Vite's top-level `devtools` option, so `vite: { devtools: false }` turns it off.
- `client.devtools.open()` / `close()` / `toggle()` still exist and now drive the Vite DevTools panel.
- The static assets RPCs `getStaticAssets`, `getImageMeta`, `getTextAssetContent`, `writeStaticAssets`, `deleteStaticAsset` and `renameStaticAsset`, together with the `AssetInfo`, `AssetEntry`, `AssetType` and `ImageMeta` types. The Assets tab is now [`@devframes/plugin-assets`](https://npmx.dev/package/@devframes/plugin-assets).

### Peer dependencies

`@nuxt/devtools` requires Vite `^8.1.5` (was `>=6.0`) and `@nuxt/kit` 4 or 5. Nitro v2 (`nitropack`, Nuxt 4) and Nitro v3 (`nitro`, Nuxt 5) are both optional peers; the one your user's Nuxt installs is the one that gets used.

Move the peer range to a named catalog.

This peer dependency uses a raw semver range. Store the supported range in a separate named catalog, then reference that catalog here. Keep the types catalog entry for the development dependency.

As per coding guidelines, “When adding a dependency, reference it as catalog:<name> in the package's package.json rather than pinning a raw version.” pnpm supports catalog: in peerDependencies. (pnpm.io)

Proposed change 
-    "unstorage": "^1.0.0 || ^2.0.0-0",
+    "unstorage": "catalog:unstorage-peer",
 catalogs:
+  unstorage-peer:
+    unstorage: ^1.0.0 || ^2.0.0-0

Review comment at @packages/devtools/package.json at line 38:
Move the unstorage peer range from the raw semver value in peerDependencies to a
named unstorage-peer catalog entry, and reference it there as
catalog:unstorage-peer. Keep the existing types catalog entry for the
development dependency.
