Refresh JWT correctly

[brucetony]

Summary by CodeRabbit

• Bug Fixes

  • Improved sign-in session recovery when sessions or token refreshes encounter errors.
  • Prevented duplicate simultaneous token refreshes and improved handling of expired or unavailable refresh tokens.
  • Preserved valid sessions more reliably by correcting token expiry calculations and refresh timing.
  • Authentication errors are now surfaced consistently to the application for clearer recovery behavior.

• Tests

  • Added coverage for concurrent refresh requests, retry behavior, and refresh failures.

📝 Walkthrough

Walkthrough

The change updates server-side OAuth token refresh, propagates refresh errors through sessions, deduplicates client refresh calls, removes the token route, adds related tests and session typing, and sets the initial release version to 1.0.0.

Changes

Authentication refresh flow

Layer / File(s)	Summary
Server refresh infrastructure server/routes/flame/api/auth/[...].ts	Token endpoint discovery is cached. Refresh attempts are deduplicated per refresh token. JWT expiry parsing and second-based expiry calculations are added.
Session error propagation server/routes/flame/api/auth/[...].ts, nuxt-auth.d.ts, server/routes/flame/api/token.get.ts	Refresh failures return RefreshAccessTokenError through JWT and session callbacks. The session type adds error?: string. The token route is removed.
Client refresh coordination and validation app/composables/useAuthRefresh.ts, app/plugins/api.ts, test/composables/useAuthRefresh.test.ts	Concurrent client refresh calls share one promise. API requests handle session errors and failed refreshes through sign-in. Tests cover shared, sequential, and failed refreshes.

Release configuration

Layer / File(s)	Summary
Initial release version release-please-config.json	The configuration sets release-as to 1.0.0 and retains the Node release type.

Merge Risk: 🟡 Moderate · up to f3c61

Later releases may continue targeting 1.0.0, and a request can proceed with a stale access token after sign-in navigation falls back. Address these issues before merging.

In `@app/plugins/api.ts`:
- Line 49: Update the OAuth sign-in branches in onRequest to return immediately
after each signIn call, including the branch using the failed-refresh
data.value, so execution cannot continue with a stale errored session or send
its accessToken.

In `@release-please-config.json`:
- Line 9: Remove the fixed release-as configuration entry from the packages
manifest configuration so subsequent release runs calculate versions from
conventional commits after the initial 1.0.0 release.
