- Register requestid.New() as first middleware in buildMiddlewareChain
(before AccessLog) so the ID is available for logging
- Add SetRequestIDHeader() in proxy/headers.go to propagate X-Request-ID
to upstream via proxy forwarding
- Call SetRequestIDHeader in header_modifier.go after SetForwardedHeaders
- Import requestid package in middleware_builder and proxy/headers
Scripts with Route config are handled by LocationEngine, so skip them
in buildLuaMiddlewares to avoid duplicate processing.
