Changes

perf(ui): migrate FileListView to Virtual ListView (LVS_OWNERDATA)

Drastically improves UI responsiveness and eliminates freezing when loading,
filtering, and displaying massive datasets (100,000+ files). By switching
to a Virtual ListView, we bypass the immense memory and CPU overhead of
allocating thousands of Win32 LVITEMW structures.
Key changes:

• Implemented LVN_GETDISPINFOW handler to supply display text dynamically
  on-demand via safe UTF-16 buffer manipulation.
• Replaced LVM_INSERTITEM and LVM_SETITEM with LVM_SETITEMCOUNT and
  LVM_REDRAWITEMS for instant UI updates.
• Introduced filtered_items index mapping in AppState to manage
  search/filter states natively in Rust without rebuilding UI elements.
• Replaced the slow Win32 LVM_SORTITEMS with blazing-fast native Rust
  sorting over the index map.
• Refactored worker thread IPC to track progress using immutable item_id (u32)
  instead of volatile UI row_idx. This prevents data corruption or crashes
  if the user sorts or searches while a compression job is actively running.
