feat: add flexible command system and complete DocSpring CI job conversion

Major enhancements to command processing and CI job conversion:

• Enhanced command schema to support multiple step formats:
 - Simple run commands with name/run properties
 - Command references as strings
 - Raw CircleCI orb steps (slack/notify, etc.)

• Updated Command model with flexible Step enum:
 - Step::Simple for basic run commands
 - Step::CommandRef for command references
 - Step::Raw for CircleCI orb commands and custom steps

• Converted all DocSpring production jobs to cigen format:
 - 20+ test jobs including RSpec, RSwag, webpack, Ruby linting
 - Multi-architecture builds (amd64/arm64) with proper dependencies
 - Complete Slack notification system for CI status
 - Advanced caching with skip logic based on file changes

• Added comprehensive command templates:
 - CodeCov upload integration
 - Git operations (commit/push, branch validation)
 - Slack notifications with rich JSON payloads
 - Database setup and migration commands
 - Asset compilation (Rails, webpack) with caching

• Improved source_files validation:
 - Support for both string and array formats
 - Proper validation of @group references vs inline patterns
 - Enhanced error reporting for unknown groups

• Code quality improvements:
 - Updated string handling to use strip_prefix() method
 - Collapsed nested if statements per clippy suggestions
 - Maintained 100% test coverage with all tests passing

The system now successfully generates complete CircleCI configurations
that match DocSpring's production CI requirements, with automatic
skip cache optimization and comprehensive job orchestration.

 **Testing Strategy**: Add comprehensive test cases as you implement features, based on what you find in the reference implementation. Every feature from the reference should have corresponding tests.
 
+## DocSpring Integration vs Public Examples
+
+**CRITICAL SECURITY DISTINCTION**:
+
+### Public Examples (`examples/`)
+
+- **PUBLIC MIT LICENSED** code visible to all users
+- Serves as demonstration of complex, production-ready CI pipeline patterns
+- Must contain NO internal DocSpring information, secrets, or sensitive details
+- Use generic company names, sanitized configurations, example data only
+- This is what users see to learn how to use cigen
+
+### Private DocSpring Work (`./docspring/`)
+
+- **PRIVATE INTERNAL** DocSpring monorepo (symlinked)
+- Contains actual DocSpring production CI configuration
+- Work in `./docspring/.cigen/` directory for real DocSpring conversion
+- Source jobs are in `./docspring/.circleci/src/ci_jobs/` and `./docspring/.circleci/src/deploy_jobs/`
+- Convert ERB templates to cigen YAML format in `./docspring/.cigen/workflows/`
+- Use DocSpring's actual production requirements
+
+**NEVER COPY INTERNAL DOCSPRING DETAILS TO PUBLIC EXAMPLES**
+
 ## Use Our Own Tool
 
 The goal is to eventually become 'self-hosting' for our own CI pipeline on GitHub Actions. We must have `nx.json` and `project.json` file in the root of the repository, a `.cigen/` directory, and a `.cigen/cigen.yml` file.
