## Description

---

Settings defaults, a schema factory, and assembled relay HTTP groups are exported without external consumers.

Keep those runtime implementation values private. Preserve the settings and relay schemas and all exported types. No schema aliases or checkpoint consumers change. This PR now touches only settings.ts and relay.ts.

Verification: contracts and consumer typechecks pass; existing contracts tests and the integrated Knip gate pass. No existing tests were changed or removed.

Follows [#10169](https://github.com/pingdotgg/t3code/pull/10169).

> [!NOTE]
> ### Make `relay` API groups and `settings` defaults module-local in contracts
> Changes the seven relay HTTP API groups in [relay.ts](https://github.com/pingdotgg/t3code/pull/10170/files#diff-cb107044ca7f6b82daab8e559dd6407c25ff0c6fdb488cc9e1b58ebd31ed8310) from exported bindings to module-local bindings; their endpoints, annotations, and middleware are unchanged. Also makes the default settings constants and the `makeProviderSettingsSchema` factory in [settings.ts](https://github.com/pingdotgg/t3code/pull/10170/files#diff-82d7525e9c2a6a61cd5d416ceaeba40992140373eb7ac00fa3a91c2edd00bc3c) module-local; types and values are unchanged.
> - Risk: removes these symbols from the package's public API; any out-of-tree code importing `RelayHealthGroup`, `RelayMetadataGroup`, `RelayMobileGroup`, `RelayClientGroup`, `RelayTokenGroup`, `RelayDpopClientGroup`, `RelayServerGroup`, `DEFAULT_TIMESTAMP_FORMAT`, `DEFAULT_DIFF_LAYOUT`, `DEFAULT_SIDEBAR_PROJECT_GROUPING_MODE`, `DEFAULT_SIDEBAR_THREAD_PREVIEW_COUNT`, `DEFAULT_SIDEBAR_AUTO_SETTLE_AFTER_DAYS`, `DEFAULT_GLASS_OPACITY`, `DEFAULT_APPEARANCE_CONTRAST`, `DEFAULT_PANEL_ANIMATION_DURATION_MS`, `DEFAULT_TERMINAL_FONT_SIZE`, `DEFAULT_QUIT_CONFIRMATION_MODE`, or `makeProviderSettingsSchema` will fail to compile.
