Saxon Fletcher 7c4872ad32 Add Studio ExplorerQuery shell (#48926)
## Summary

Adds the Studio-owned `ExplorerQuery` shell used by notebooks, SQL
snippets, dedicated query tabs, and assistant query blocks within
Explorer.

- provides framed embedded and full-height viewport roots
- provides composable editor, results, and footer layout regions
- keeps result content responsible for its own scrolling while the
results region fills remaining height
- remains presentational: query models, execution, source resolution,
persistence, and result rendering stay external
- expands the project-local Explorer agent skill with composition and
sizing guidance
- adds focused Studio component tests

All files are scoped to `apps/studio`; this PR no longer changes
`ui-patterns` or the design-system app.

## Stack

- Base: #48925
- Next: #48961
- This PR targets `chore/toolbar-component`, so its review diff contains
only the query shell layer.

## Validation

- `pnpm --filter studio exec vitest run
components/interfaces/Explorer/ExplorerQuery/ExplorerQuery.test.tsx
components/interfaces/Explorer/ExplorerToolbar/ExplorerToolbar.test.tsx`
— 6 tests passed
- `pnpm --filter studio typecheck`
- Prettier
- `git diff --check`

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}
