🚀 v1.0.0 - Initial Public Release

CodeVerdict is an open-source coding exam platform with NestJS + Vue 3, ICPC-scored leaderboards, Monaco editor, and self-hosted Judge0 code execution. Self-host for your university, bootcamp, or hiring pipeline.

✨ Highlights

• 🧑‍Judge0 code execution — batch submission with base64 encoding and token polling
• 🏆 ICPC-scored live leaderboard — PostgreSQL materialized view with O(1) rank queries and pessimistic write locks
• ⏱️ Timed exams — server-synced countdown (manipulation-proof) + ExamWindowGuard
• 📝 MCQ + coding — mixed exam formats in a single session
• 🎨 White-label branding — app name, logo, colors, copyright all via env vars
• 🐳 Single-container deploy — multi-stage Dockerfile, Brotli-compressed assets, runs as non-root
• 🚂 One-click Railway deploy — railway.toml included
