CLD-01: Deploy Taskdeck to managed cloud platform (Railway/Render)

[Chris0Jeky]

Summary

Deploy the existing Docker Compose setup to a managed platform for hosted cloud access.

Acceptance Criteria

• Taskdeck API + frontend running on a managed platform (Railway or Render)
• Accessible via HTTPS on a public URL
• Persistent volume for SQLite database
• Environment variables configured (JWT secret, CORS origins, LLM config)
• Health check endpoint monitored
• Automatic restart on crash

Implementation Notes

• Start with Railway (simplest Docker deployment, automatic TLS)
• Use the existing deploy/docker-compose.yml as reference
• May need to consolidate API + frontend into a single service for simpler deployment
• Estimated cost: $6-10/month for 100 users
