Longbridge credentials are prefixed with their data center: `us_…` for the US data center and `ap_…` for Asia-Pacific. This applies to the OAuth access token and, in legacy API-key mode, to the `app_key`, `app_secret`, and `access_token`. The API gateway routes a request to the matching data center via the `x-dc-region` header, defaulting to `ap` when absent. - `longbridge-geo`: add `DcRegion` (`from_credential` / `from_credentials` / `as_str`) and the `DC_REGION_HEADER` constant, re-exported through `longbridge-httpcli` and the crate root. - The HTTP client and the quote/trade WebSocket upgrade now auto-inject `x-dc-region` derived from the auth credentials, so US-region tokens reach the US data center with no caller changes. An explicitly-set header (e.g. via a custom header or `Config::dc_region`) is preserved. - `Config::dc_region()` remains as an explicit override.

The `us_`/`ap_` prefix on an access token is region metadata used to derive the `x-dc-region` routing header — it is not part of the verifiable bearer credential. Sending the full `us_…` token in `Authorization: Bearer` makes the gateway reject it (401102 token verification failed). Strip the region prefix before building the `Authorization` header (deriving the region from the prefix first), so the gateway verifies the bare token and routes by `x-dc-region`. WebSocket auth is unaffected: it uses an OTP fetched over this same HTTP path. Add `DcRegion::strip_region_prefix`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Adds first-class support for the
x-dc-regiondata-center routing header.Longbridge access tokens are prefixed with their region (
us_…/ap_…). The API gateway routes a request to the matching data center based on thex-dc-regionheader; an absent header defaults toap.Changes
regionmodule:DcRegionenum withfrom_access_token(prefixus_→Us, otherwiseAp) andas_str("us"/"ap"), plus theDC_REGION_HEADERconstant.Config::dc_region()convenience that setsx-dc-regionon every HTTP and WebSocket upgrade request (via the existingcustom_headerspath).DcRegionandDC_REGION_HEADERat the crate root.Consumers (longbridge-terminal, longbridge-mcp) derive the region from their access token and attach the header so US-region tokens reach the US data center. US and AP share the same OAuth endpoints — only the routing header differs.
