33-37: Avoid hardcoding 2026 in skill rules/examples.

These rules will drift next year and can generate stale guidance. Prefer a dynamic placeholder like CURRENT_YEAR in instructions/examples, then resolve it at runtime when applying updates.

Proposed doc refactor

- - **Single past year** (e.g., `Copyright (C) 2024`) → Update to range: `Copyright (C) 2024-2026`
+ - **Single past year** (e.g., `Copyright (C) 2024`) → Update to range: `Copyright (C) 2024-CURRENT_YEAR`

- - **Range ending before current year** (e.g., `Copyright (C) 2024-2025`) → Update end year: `Copyright (C) 2024-2026`
+ - **Range ending before current year** (e.g., `Copyright (C) 2024-2025`) → Update end year: `Copyright (C) 2024-CURRENT_YEAR`

-# Copyright (C) 2026 Red Hat, Inc.
+# Copyright (C) CURRENT_YEAR Red Hat, Inc.

-* Copyright (C) 2026 Red Hat, Inc.
+* Copyright (C) CURRENT_YEAR Red Hat, Inc.

-- Use the current year (2026) in the copyright notice
+- Use the current year (`CURRENT_YEAR`) in the copyright notice
