v1.6.10 - Fix GameKB infinite retry storm on LLM 404

Deployment sequence initiated for version 1.6.10. This transmission contains critical updates to the core engine and agentic capabilities.

Transmission Details

• GameKB keybind fetch failures (404, timeout, etc.) now enforce a 5-minute per-game cooldown before retrying
• Cooldown check added at both thread-spawn site (identify_game) and background worker to guarantee no storm
• Successful fetches clear the failure record so retries resume normally after an endpoint recovers
