Use BMCLAPI mirror & update build

Route Minecraft/Fabric/Forge downloads through BMCLAPI mirror and update installer logic. Added mirror rewrite utility (rewriteToMirror), mirror-aware downloadFile, and mirrorFetch; switched version manifest and metadata endpoints to bmclapi2.bangbang93.com and wired maven/assets hosts into xmcl/installer calls. Cleaned up compiled electron JS files and consolidated runtime files under electron-dist; updated electron-builder.yml (compression, asar, NSIS settings, license/installer assets and languages). Minor env/path changes (VITE_APP_ICON paths), added .npmrc (electron_mirror), new Koring.yml, pnpm-workspace and public installer assets. Also added/updated multiple frontend pages, store components, and TypeScript handlers to integrate the changes.
