v1.9.7 - Complete ARAM In-Game AI Coaching & Multi-Signal Detection Fix

Bug Fixes

• In-Game Fast Coaching (ai-coaching) Prompt Fix: Fixed in-game periodic AI coaching tips mentioning 'Void Grubs up' at 8:00 during ARAM matches by using an ARAM-specific system prompt in main.js that omits getGameRulesText() and forbids mentioning Void Grubs, Scuttle Crab, Dragon, Baron, or junglers.
• Relevance Filter Safeguard: Added immediate rejection filter in isCoachStatementRelevant() for any advice containing SR objective/jungle keywords (grub, dragon, baron, herald, scuttle, jungle, roam) when in ARAM mode.
• Multi-Signal ARAM Auto-Detection: Expanded ARAM detection in onGameData() to check gameMode, mapName ('Howling Abyss' / 'Map12'), mapNumber === 12, and player position arrays.
