fix(httputil): rename error body field platformCode → platform_code (#2)

errorBody() map key corrected from "platformCode" to "platform_code" to
match the OpenAPI spec snake_case convention. All HTTP error responses
produced by Error(w, err) now emit "platform_code" in the JSON body.
PR.md added to .gitignore.
Depends on xerrors v1.0.2 (go.mod bumped in follow-up commit after xerrors tag).
