Complete CI/CD documentation

Ensure all CI/CD documentation is comprehensive and technically accurate, covering complete workflows and tooling capabilities. Incomplete or incorrect documentation leads to deployment failures, misconfigurations, and developer confusion.

Documentation should include:

• All deployment scenarios (initial deployment, rollbacks, parameter retrieval)
• Accurate build tool configurations and supported formats
• Complete feature coverage without assumptions

For example, when documenting deployment buckets, include all use cases:

# Deployment Bucket
Storage for Lambda code, CloudFormation templates, and other resources 
required for service deployment, service rollback, and efficient parameter retrieval.

When documenting build configurations, verify technical accuracy:

**Note:** Build output format can be configured for both CommonJS and ESM. 
See esbuild documentation for format options.

This prevents developers from making incorrect assumptions that could cause deployment issues or require workarounds.
