Execute Refactor Item

Apply the provided refactor item to the codebase, following the project's conventions and architecture.

The Job

1. Read the refactor item (id, title, description, rationale) carefully.
2. Review the project context to understand conventions, tech stack, and module structure.
3. Plan the change: identify which files to create or modify and how the change fits into the existing architecture.
4. Apply the refactor:
   • Make the changes described in the item's description.
   • Ensure the code compiles / type-checks without errors after the change.
   • Run any quality checks defined in the project context and fix failures before finishing.
5. Do not commit — the calling command manages git operations.
