feat: 扩展日志类型，支持 JVM 崩溃与启动器日志

LogType 新增 JvmCrash 与 LauncherLog，使崩溃弹窗能列出
hs_err_pid*.log、launcher_log.txt、latest_stdout.log 等日志。

- 新增 log_directories_for_type 与 is_log_file_for_type，统一
  各日志类型的目录解析与文件名筛选
- 新增 isolated_minecraft_root，兼容 versions 版本隔离布局
- get_logs 追加 JvmCrash 与 LauncherLog 两类采集
- get_logs_by_filename / get_output_by_filename /
  delete_logs_by_filename 改用目录列表按存在性查找
- get_logs_from_type 遍历多目录并按文件名去重
