Append an entry to the game log with current game state context.
bash
source scripts/executor.sh game_log "**Decision:** [what was decided and why] **Action:** [what was done] **Result:** [what happened] Tags: [comma-separated keywords for searchability]"
Include tags that would help find this entry later. Good tags: map names, NPC names, quest names, action types (combat, dialogue, exploration, barter, puzzle).
