Logger

Internal logger for Lean4Game.

It does two things:

1. Collects usage statistics from open Lean4Game sessions.
2. Checks which installed games are inactive and can eventually be cleaned up.

Usage statistics

The Logger reads the Lean4Game sessions API and stores daily country/game statistics.

Game activity cleanup

Lean4Game stores when a game was last seen, played, or uploaded. The Logger reads this data once per day and calculates the game status.

Stages:

active -> inactive -> deletion_due -> moved to .trash -> deleted

(trash entries are deleted after GAME_TRASH_RETENTION_DAYS).

The Logger writes reports to:

Activity/logs/activity-status.json
Activity/logs/cleanup-status.json

The Logger skips protected games, currently open games, invalid paths, symlinks, and missing folders.
