refactor(reports): restructure contributors with subsections

Add main 'Contributors' header with two subsections:
- 'New Lights' for first-time contributors (with gold highlight)
- 'Wayfinders' for returning contributors

This improves navigation and clearly distinguishes newcomers from
veteran contributors while maintaining the Destiny 2 theme.
