🐛 BUG: concurrent processes race the single-use refresh token (read → exchange → write is unlocked); a lost race kills the refresh chain until interactive re-login
## Summary `refreshToken()` still has a process-crossing race that #13910 did not close: the read → token-endpoint exchange → `writeFileSync` sequence on the shared auth config (`~/Library/Preferences/.wrangler/config/default.toml` on macOS) is not serialized or atomic.
