SopPillars 1.0.3

• Added stale arena state recovery.
• Arenas can now auto-heal back to WAITING if they were left in a broken runtime state without an active match.
• Improved reset and shutdown cleanup to normalize idle arena states.
• Hardened match finish flow with safer restore/finalization handling.
• Even if arena restore throws during cleanup, the arena is now forced back into WAITING and saved.
• Updated SopLib dependency to 1.0.2.
