refactor: create docker-stack workspace for deployment configs

Created dedicated workspace for Docker deployment configurations and scripts.
Improves organization by grouping all deployment-related files together.

## New Structure
- docker-stack/: Docker Compose files and deployment scripts
  - docker-compose-standalone.yaml
  - docker-compose-swarm.yml
  - docker-compose-debug.yml
  - deploy-standalone.sh
  - deploy-swarm.sh
  - README.md (deployment documentation)
  - package.json

## Changes
- Moved all docker-compose YAML files to docker-stack/
- Moved deploy scripts to docker-stack/
- Updated VS Code workspace to include docker-stack
- Updated documentation (README, CLAUDE.md)

## Deployment Workflow
1. Build: `cd web-app && ./build.sh 2.20.0`
2. Deploy: `cd docker-stack && ./deploy-standalone.sh 2.20.0`
