Debt reduction and maintenance

## Why

Ongoing efforts focused on reducing technical debt and maintaining the codebase through continuous improvement, addressing bugs, and creating new distributions. This ensures the system remains stable, maintainable, and adaptable to evolving requirements.

The issue names no files, tests, or entry points and describes an ongoing maintenance program rather than one concrete task. Start by identifying a specific bug, technical-debt item, or distribution change in the Rust codebase, then define the affected area and a testable completion condition before beginning.
