## 🐛 Bug Fixes & Improvements

### **@c15t/dev-tools**

Added official TanStack Devtools support for `@c15t/dev-tools`.

This release stabilizes the existing integration and makes it ready to document publicly:

* Added the `c15tDevtools()` plugin factory for TanStack Devtools, while keeping `c15tDevtoolsPlugin()` as a backward-compatible alias
* Switched the integration to TanStack Devtools' React plugin API instead of the previous custom mount pattern
* Kept the embedded c15t panel connected across TanStack tab switches so it does not drop the store connection when the plugin view remounts
* Updated the embedded panel styling to better match TanStack Devtools
* Added demo coverage for repro and regression testing

#### Usage

```tsx
import { TanStackDevtools } from '@tanstack/react-devtools';
import { ReactQueryDevtoolsPanel } from '@tanstack/react-query-devtools';
import { c15tDevtools } from '@c15t/dev-tools/tanstack';

export function AppDevtools() {
  return (
    <TanStackDevtools
      plugins={[
        {
          name: 'TanStack Query',
          render: <ReactQueryDevtoolsPanel />,
        },
        c15tDevtools({
          defaultOpen: true,
        }),
      ]}
    />
  );
}
```

### **@c15t/cli**

Improved Tailwind v4 stylesheet import ordering when the CLI adds c15t stylesheets to app-level CSS files.

This keeps c15t imports at the end of the top-level `@import` block so preset styles such as Fumadocs load first and do not override c15t theme tokens unexpectedly.
