Add support for deploying stacks from GitHub template repositories. Template names like "mittwald/n8n" are automatically converted to "mittwald/stack-template-n8n" repositories. Fetches both docker-compose.yml and .env files from the main branch. Features: - New --from-template flag (mutually exclusive with --compose-file) - Custom error types for better error handling (TemplateFileNotFoundError, GitHubRateLimitError, TemplateNetworkError) - Environment variable precedence: template .env < process.env < --env-file - Comprehensive unit tests with axios mocking 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>

Adds support for deploying stacks directly from GitHub template repositories using the new
--from-templateflag.This enables users to quickly deploy pre-configured application stacks without manually managing docker-compose files locally. Template names like
mittwald/n8nautomatically resolve to the correspondingmittwald/stack-template-n8nrepository.What This Enables
Quick Stack Deployment
Deploy popular applications instantly from curated templates:
Template Repository Naming
Template names follow a simple convention:
mittwald/n8ngithub.com/mittwald/stack-template-n8nEnvironment Configuration
Templates can include default environment variables via
.envfiles, which can be overridden:Environment Variable Priority (from lowest to highest):
