Rewrites 339 TypeScript calls across 50 pages from the rc.5 `method({ namespace, body })` form to the shipped `method(namespace, { ... })` form, and aligns field names with the live v5 spec: `attach` to `include`, `authUrl` to `authorization`, `lastSync` to `latestRun`, `deletedCount` to `count`, and the paginated `namespaces.list()`.
Renames container tags to namespaces across concepts, connectors, integrations and snippets. The namespace pages keep container tag in the description, search keywords and a rename note so old searches still land, and the v3 reference page points at v5.
The migration guide's SDK table now covers both 5.0.0 SDKs, and the SDK integration page uses the real client options (`baseUrl`, `timeoutInSeconds`, `maxRetries`) and error classes.
Add Legacy and Latest reference versions, organize the V5 operations by workflow, and introduce focused overview pages backed by the generated V5 OpenAPI document.
