v4.1.0

What changed

• Added swift-style-tooling-workflow as a new active skill for SwiftLint and SwiftFormat integration across CLI, Xcode build phases, Xcode source-editor workflows, Swift Package plugins, Git hooks, GitHub Actions, and SwiftFormat config export.
• Added a deterministic helper for exporting SwiftFormat for Xcode shared settings into a checked-in .swiftformat file.
• Updated the active skill surface, maintainer workflow atlas, validator, and tests so the new style-tooling skill is part of the canonical repo contract.
• Tightened the main xcode-app-project-workflow handoff guidance so it explicitly points style-tooling requests at swift-style-tooling-workflow.
• Expanded customization-system validation to require references/customization-flow.md and to audit customization-template paths across the full active skill surface.

Breaking changes

• None.

Migration / upgrade notes

• Install swift-style-tooling-workflow when you want a dedicated workflow for SwiftLint or SwiftFormat setup instead of relying on bootstrap or execution skills.
• Re-run any local docs or validation tooling that assumes the active skill list is fixed at six skills; the active public surface now includes seven skills.
