Summary

The uv-projects.instructions.md file lists black in the always-install tool set, but the repository uses ruff as the Python formatter. This inconsistency causes agents and contributors to install the wrong formatter.

Context

The coding standards instructions at .github/instructions/coding-standards/uv-projects.instructions.md specify tools that should always be installed in Python projects. The list includes black as the formatter, but the repository's actual convention (established in PR #868 and the Python coding standards) uses ruff format instead. Ruff handles both linting and formatting, making black redundant and conflicting.

Changes Required

Acceptance Criteria

• uv-projects.instructions.md lists ruff instead of black as the formatter
• No references to black remain in the instructions file
• Instructions are consistent with actual project tooling
