v0.8.97-pre.1

https://github.com/chen08209/FlClash/actions/runs/33142349786

Features
• Popup menus grow out of the button that opened them
• Proxy groups show their type and their cards slide in one after another when expanded
• Provider lists scroll smoothly, subscriptions show full usage details, and sheets size to the page in view
• Rebuilt the interface on material_ui and simplified the overwrite flow
• Rebuilt the core, provider, and application layers

Bug Fixes
• A language switch now reaches the tray menu, VPN notification, and shortcut label
• Backups clean up their temp files, group jumps land right while searching, and the tray stops replaying stale speeds
• Stalls, double starts, and refused starts no longer take the tunnel down
• Elevated runs and profile providers stop leaving files outside their owner, and narrow windows stay usable
• Recovery after a crash no longer waits on the crash reporter to start
