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.
## Summary
The billing guide omits Max and contradicts the pricing page about Gmail access. Add Max ($100/month with $130 in monthly credits), correct the plan feature matrix, list all six current coding plugins as available on Free with credit-consuming usage, and update both remaining Scale-only requirements on the Gmail connector page to Max or above.
Clarify that paid-plan automatic top-up limits cap automatic credit purchases, not the total invoice, and correct the documented auto-topup update endpoint from PATCH to POST.

## Validation
- Compared prices, credit inclusions, connector gates, and top-up behavior with the console and API source on main. Verified that all six coding plugins are on FREE_TIER_PLUGIN_IDS and the authentication route bypasses the generic Pro gate for them. Usage still consumes plan credits.
- Checked Markdown table column counts and required Max entries; `git diff --check` passed.
- Confirmed the Gmail introduction, prerequisite, and troubleshooting requirement consistently say Max or above.
- Documentation-only change. A full Mintlify build was not run.
Crawler-access verification, AI-search benchmarking, and analytics/measurement work are excluded from this PR.
