Changes
Core Matchmaking Engine: Developed MatchmakingService which handles player queues, ELO calculations (K-Factor 32), and match quality scoring.

Redis Integration: Utilized Redis Sorted Sets for efficient queue management and Hashes for persistent player metadata, ensuring horizontal scalability across backend instances.

Dynamic Search Expansion: Implemented an algorithm that expands the ELO search radius as player wait time increases to balance match quality with speed.

WebSocket Handlers: Created real-time event emitters for matchmaking:found, matchmaking:queue, and matchmaking:cancelled events.

REST API Endpoints: Added a new MatchmakingController providing endpoints for joining/leaving the queue, checking status, and the match acceptance/decline flow.

Premium Priority: Integrated a priority system that grants premium players shorter wait times via a join-time offset in the Redis sorted set.

Invitation Lifecycle: Implemented a 30-second match invitation expiry with cleanup logic to prevent stale match sessions.

Testing
[x] Unit tests pass (npm test)
[x] Manually tested locally using Postman for REST endpoints and a WebSocket client for real-time events.
[x] Verified ELO range expansion logic under simulated high-latency/low-player conditions.
Checklist
[x] Code follows project conventions
[x] No secrets or PII committed
[x] CI passes
