Subject: [PATCH] feat(install): resolve GEO assets via GitHub mirror proxy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mihomo 默认从 raw.githubusercontent.com 下载 GEO 数据库
(https://github.com/MetaCubeX/mihomo/blob/Meta/config/config.go#L570-L575)，
在大部分国内网络环境下无法获取，导致启动失败。

复现方式：

  cat >/tmp/geosite-test.yaml <<'YAML'
  mixed-port: 7890
  allow-lan: false
  mode: rule
  log-level: debug
  proxies: []
  proxy-groups: []
  rules:
    - GEOSITE,cn,DIRECT
  YAML

  /root/clash/runtime/bin/mihomo -t -f /tmp/geosite-test.yaml -d /root/clash/runtime

报错：

  INFO Start initial configuration in progress
  INFO Geodata Loader mode: memconservative
  INFO Geosite Matcher implementation: succinct
  INFO Can't find GeoSite.dat, start download
  ERRO can't initial GeoSite: can't download GeoSite.dat:
       Get "https://release-assets.githubusercontent.com/...": context deadline exceeded
  ERRO rules[0] [GEOSITE,cn,DIRECT] error: can't download GeoSite.dat: context deadline exceeded
  configuration file /tmp/geosite-test.yaml test failed

新增 resolve_geo_assets 在安装阶段通过 GitHub 镜像池预下载全部 GEO 资产
到 RUNTIME_DIR，避免 mihomo 启动时因网络不通而失败。

资产列表对齐 mihomo GeoXUrl 默认值：
  Country.mmdb / geoip.metadb / GeoLite2-ASN.mmdb / GeoIP.dat / GeoSite.dat

- 复用 copy_bundled_asset 优先从 resources/geo/ 复制
- 本地不存在时通过 download_file 走 default_github_mirror_pool 镜像加速
- copy_bundled_asset 增加 $RESOURCE_DIR/$category/$file 搜索路径
