fix(complement-race): balance AI speeds to match original implementation

Fixes AI opponents racing away too fast and ending the game in 2 seconds by restoring the original balanced speeds and mode-specific multipliers.

Changes:
- Reduce AI base speeds from 0.8-1.2 to 0.32 (Swift AI) and 0.2 (Math Bot)
- Add mode-specific speedMultipliers: practice (0.7), sprint (0.9), survival (1.0)
- Update AI names to match original: "Swift AI" and "Math Bot"

The original system uses much lower base speeds combined with:
- Random variance (0.6-1.4x per update)
- Rubber-banding (2x speed when >10 units behind)
- Adaptive difficulty adjustments based on player performance

This makes AI opponents challenging but fair, adapting to player skill rather than just racing ahead at fixed high speeds.
