Remove the devframes entries from externals.inline.

The eight package names are pushed into config.externals.inline, the list that Nitro bundles. The existing test uses externals.inline on Nitro v2 and leaves its boolean noExternals alone asserts that this list equals ['vue', runtime path], so it fails. The entries also force these packages to be bundled, which contradicts the stated goal of keeping them external.

Review comment at @packages/devtools/src/module-main.ts around lines 340 - 349:
Remove the `@devframes/*` and `devframe` entries from `config.externals.inline`
so these packages remain external and the existing Nitro v2 assertion continues
to pass. Preserve the handling of `externals.inline` for other dependencies.
