- Replace __DiscordOAuthState cookie (blocked by third-party cookie policies)
with in-memory DiscordOAuthStateStore singleton
- State is created server-side and validated on callback, eliminating
cross-site cookie transmission issues entirely
- Removed CryptographicOperations dependency from Program.cs
Bump version → 2.8.1
