## Summary `ExternalAuthRefresher` was still shaped around external ChatGPT auth: `ExternalAuthTokens` always implied ChatGPT account metadata even when a caller only needed a bearer token. This PR generalizes that contract so bearer-only sources are first-class, while keeping the existing ChatGPT paths strict anywhere we persist or rebuild ChatGPT auth state. ## Motivation This is the first step toward #15189. The follow-on provider-auth work needs one shared external-auth contract that can do both of these things: - resolve the current bearer token before a request is sent - return a refreshed bearer token after a `401` That should not require a second token result type just because there is no ChatGPT account metadata attached. ## What Changed - change `ExternalAuthTokens` to carry `access_token` plus optional `ExternalAuthChatgptMetadata` - add helper constructors for bearer-only tokens and ChatGPT-backed tokens - add `ExternalAuthRefresher::resolve()` with a default no-op implementation so refreshers can optionally provide the current token before a request is sent - keep ChatGPT-only persistence strict by continuing to require ChatGPT metadata anywhere the login layer seeds or reloads ChatGPT auth state - update the app-server bridge to construct the new token shape for external ChatGPT auth refreshes ## Testing - `cargo test -p codex-login` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).
