chore: add development configuration files

Add .env with default development settings and .vscode debug configurations for easier local development.

- .env: Development environment variables (PORT, DEBUG, PULL_INTERVAL)
- .vscode/launch.json: Debug configurations for server and Jest tests
- .vscode/settings.json: Jest integration settings
