Enqvy	81c118c9b2	customizable packet fragmentation settings (#9597 ) * first changes * fix: use ItemsSource for fragment packets ComboBox so value saves correctly * feat: add customizable packet fragmentation for Xray-core - Add fragment settings in Core tab: Packets (dropdown), Length (range), Interval (range), MaxSplit (0-10000) - Support both 'from-to' (e.g., 50-100) and single value (e.g., 50) formats for Length, Interval, and MaxSplit - Validation with shortened error message: 'Invalid range format. Use from-to (e.g., 50-100).' - UI in PopupBox (materialDesign) visible only when EnableFragment is checked - Only Xray-core supported (Mihomo/sing-box fragment code removed) - Localization updated for 8 languages * fix: address 2dust review feedback - Move FragmentPacketsOptions to Global class - Remove default values from Fragment4RayItem model (set in ConfigHandler) - Fix Avalonia bindings: move ItemsSource and SelectedItem to code-behind - Update ViewModel to use Global.FragmentPacketsOptions - Remove defaults from model properties * Adjust ui --------- Co-authored-by: 2dust <31833384+2dust@users.noreply.github.com>	2026-06-22 16:00:13 +08:00
