Switching between personal and org repositories forces user to reauthorize github app #1315
Description
Problem
Currently using User OAuth tokens (ghu_...) which conflict when switching between personal and organization repositories. When authorizing for org repos, the personal repo token becomes invalid, and vice versa.
Root cause: OAuth flow creates user-scoped tokens. GitHub treats each authorization as the same user re-authorizing the same app, invalidating the previous token.
Personal repos → User Token A (ghu_zNgl...) ✅
Org repos → User Token B (ghu_jLu1...) → Token A invalidated ❌
Possible Solution
Switch to Installation Access Tokens (ghs_...) which are installation-scoped, not user-scoped. Each installation (personal, org) gets its own independent token.
