Four small UX fixes to the asset explorer: 1. Remove the no-op "View" menu (Textures/Meshes/Audio toggles + Wireframe checkbox) — none were wired to anything. Dropped ViewMode + the current_mode/ wireframe fields from ViewerState (nothing read them); the central panel already dispatches on which preview resource is populated. 2. Loading indicator — clicking a drawer item now flips FileBrowserState.loading and the central panel shows a centered spinner + "Loading <name>…" until the background read/decode applies, instead of leaving the previous item on screen with no feedback. Cleared in poll_loader_channel on FileLoaded/PakLoaded/ Error/Cancelled. 3. Drawer shows only the .pak index, not its .pNN data segments — the segments are the pack's body (loaded when the .pak is opened), so listing them (with no preview) was noise. Dropped the virtual "<stem>.pak" folder too; the .pak now sits as a normal leaf in its real directory. 4. Bottom status bar no longer overflows — horizontal_wrapped, only the source's final path component (full path on hover), file count, and a right-aligned, shortened controls hint. Removed the mode label. Viewer + formats build; all tests pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
