feat: Overhaul ranking system to support CS2 dual-architecture

Browse Source

Based on comprehensive research, CS2 implements a bifurcated ranking system:
- Premier Mode: CS Rating (numerical ELO, 0-30,000+) - launched Aug 31, 2023
- Competitive/Wingman: Skill Groups (0-18, Silver I to Global Elite)
- Legacy CS:GO: Skill Groups only (pre-Sept 27, 2023)

Changes:
- Add game_mode field to Match type ('premier' | 'competitive' | 'wingman')
- Create rankingSystem.ts utility with smart detection logic:
  * Checks match date (CS:GO legacy vs CS2)
  * Checks game_mode (Premier vs Competitive/Wingman)
  * Falls back to rating value heuristic (0-18 vs 1000+)
- Update PremierRatingBadge to use new detection logic
- Pass match context from match detail page to badge component
- Update Match and schema documentation with dual-system details
- Add research.md documenting CS2's ranking system architecture

Key dates:
- August 31, 2023: Premier Mode and CS Rating launched
- September 27, 2023: CS2 officially replaced CS:GO
