Charis 2709fa4a3e feat: pre-compile-time partials (#34028)
Partials are currently defined via MDX includes. This PR switches to pre-compile-time partials, which have a new syntax:

```
<$Partial path="path/to/file.mdx" />
```

## Rationale

This produces two improvements:

1. Partial substitution can occur in pipelines that don't use MDX compilation. For example, we can now do partial substitution before building the search index, so partial content will also be indexed.
2. After the App Router migration, the MDXProviders should've been deprecated, but were kept around for the sole reason of making partials work, and leading to us shipping unnecessary client-side code. We get a minor decrease in overall client bundle size (5.74 MB to 5.6 MB) by getting rid of the Providers.

## Breaking changes

Besides the change to partial syntax, the arguments are also less powerful than before because we are doing string substitution and don't have the full power of JS. Defining string variables is still possible (documented in the Contributing guide), and since that's all we actually do in practice, this shouldn't be too cumbersome. There is always the escape hatch of making a custom component for more complex content reuse cases.

The fastest way to get started is to use the `supabase-js` client library which provides a convenient interface for working with Supabase from a React app.
Navigate to the React app and install `supabase-js`.

<StepHikeCompact.Details title="Query data from the app">
In `App.jsx`, create a Supabase client using your project URL and public API (anon) key:
<ProjectConfigVariables variable="url" />
<ProjectConfigVariables variable="anonKey" />
Add a `getInstruments` function to fetch the data and display the query result to the page.

function App() {
const [instruments, setInstruments] = useState([]);

async function getInstruments() {
const { data } = await supabase.from("instruments").select();
