Fixes Applied:

  1. AI Self-Crashing Bug - Increased collision buffer zones and improved trail detection
  2. Linux Dependencies - Added comprehensive installation instructions for Debian/Ubuntu, Fedora, and Arch

  Improvements Made:

  - AI now skips 30 recent trail points (up from 10) to avoid self-collision
  - Increased look-ahead distances for all difficulty levels
  - Fixed trail collision detection in pathfinding
  - Added full Linux dependency documentation

  The AI should now survive much longer and provide a better challenge. And thank you for the two PR's!
