Claude Code cbcfd9599f docs: cut 6.1.0 versions for docs, admin_docs, developer_docs, components
Snapshots all four versioned Docusaurus sections at v6.1.0. Built on
top of the version-cutting tooling work in chore/docs-cut-6.1.0-versions
so the snapshot benefits from:

- Auto-gen refresh before snapshotting (database pages from engine
  spec metadata, API reference from openapi.json, component pages
  from Storybook stories) — captured at the SHA we cut from rather
  than whatever happened to be on disk.
- Data-import freeze: country list, feature flag table, database
  diagnostics, and component metadata are copied into snapshot-local
  `_versioned_data/` dirs so the historical version doesn't silently
  mutate when the source files change.
- Depth-aware import-path rewriter that handles deeply-nested
  component MDX files referencing `../../../src/` from the snapshot.

Versioning behavior: `lastVersion` stays at `current` for every
section, so the canonical URLs (`/docs/...`, `/admin-docs/...`,
`/developer-docs/...`, `/components/...`) continue to render content
from master. The `current` version is consistently labeled "Next"
with an `unreleased` banner, and `6.1.0` is a historical pin
accessible only via its explicit version segment.

Component playground: previously `disabled: true` in versions-config.json,
now enabled and versioned. The plugin block in docusaurus.config.ts
was already gated only by the `disabled` flag, so no other code
changes were needed to bring it back online.

The frozen `databases.json` in the snapshot is the canonical 80-database
artifact from the latest committed state in master (preserved by the
generator's input-hash cache), not a fallback regenerated from a
local Flask environment.

Frontend Style Guidelines

This is a list of statements that describe how we do frontend development in Superset. While they might not be 100% true for all files in the repo, they represent the gold standard we strive towards for frontend quality and style.

  • We develop using TypeScript.
  • We use React for building components, and Redux to manage app/global state.
  • We prefer functional components to class components and use hooks for local component state.
  • We use Ant Design components from our component library whenever possible, only building our own custom components when it's required.
  • We use @emotion to provide styling for our components, co-locating styling within component files.
  • We use Jest for unit tests, React Testing Library for component tests, and Cypress for end-to-end tests.
  • We add tests for every new component or file added to the frontend.
  • We organize our repo so similar files live near each other, and tests are co-located with the files they test.
  • We prefer small, easily testable files and components.
  • We use OXC (oxlint) and Prettier to automatically fix lint errors and format the code.
    • We do not debate code formatting style in PRs, instead relying on automated tooling to enforce it.
    • If there's not a linting rule, we don't have a rule!
    • See: Linting How-Tos
  • We use React Storybook to help preview/test and stabilize our components
    • A public Storybook with components from the master branch is available here
