[bug]: fix(cli): migrate radix outputs SlotPrimitive.Slot instead of Slot.Root

[Abhirup0]

Describe the bug

Description

When running shadcn migrate radix, components using @radix-ui/react-slot are converted to import { Slot as SlotPrimitive } from "radix-ui" and const Comp = asChild ? SlotPrimitive.Slot : "button".

In shadcn v4, components standardize on import { Slot } from "radix-ui" and Slot.Root. Using SlotPrimitive.Slot causes inconsistency across registry components and breaks prop typing.

Suggested Fix

In packages/shadcn/src/migrations/migrate-radix.ts:

1. Do not alias Slot as SlotPrimitive when extracting imports.
2. Replace __SLOT_PLACEHOLDER__ with Slot.Root.

Affected component/components

Affected Files packages/shadcn/src/migrations/migrate-radix.ts: - Lines 47–52 & 85–90: Aliases Slot to SlotPrimitive - Line 440: Replaces Slot with SlotPrimitive.Slot

How to reproduce

Steps to Reproduce

1. In a project with a component using import { Slot } from "@radix-ui/react-slot".
2. Run npx shadcn@latest migrate radix.
3. Check the transformed file: it generates SlotPrimitive.Slot.
