Social Sync v0.4.0 — Security Hardening

Security First As part of the v0.4.0 release of atproto-connect (now Social Sync), I've focused heavily on the security architecture to ensure player data is protected from the start. - Encrypted Storage: Implemented AES-256-GCM encryption for all session data stored on the client. - Audit Logging: Added a comprehensive security audit log that tracks authentication attempts, rate limit violations, and session lifecycle events. - Rate Limiting: Introduced rate limiting for authentication attempts to prevent brute-force attacks. - Record Manager: Built a robust RecordManager to handle CRUD operations and batch processing for AT Protocol records. - GUI Auth: Added a preliminary GUI for authentication within the Minecraft client.
