aviyadeveloper ee5e319dad docs: project planning and architecture design 
- Add ADR.md documenting all technology stack decisions with rationale
- Create comprehensive ROADMAP.md with 10-phase implementation plan
- Add 3 architecture diagrams (AWS infrastructure, application stack, network)
- Document collaboration guidelines in `.github/copilot-instructions.md`
- Technology stack descisions: AWS, Terraform, Ansible, Docker Compose, PostgreSQL

Phase 1 establishes foundation for automated Gitea deployment with
proper decision tracking and incremental development approach.

AWS Infrastructure Diagram

This diagram shows the high-level AWS resources and their relationships.

Components

  • Route 53: DNS service that points domain to EC2 instance
  • EC2 Instance: Single VM running Docker with all application containers
  • S3 Bucket: Storage for database and application backups
  • VPC: Isolated network containing EC2 instance

Traffic Flow

  1. User accesses gitea.yourdomain.com
  2. Route 53 resolves to EC2 public IP
  3. Request hits EC2 (nginx handles SSL, proxies to Gitea)
  4. EC2 regularly backs up data to S3
