Module asset_pane 

Inspector asset-metadata pane.

When the user selects an asset in the browser, the Properties panel switches from per-entity component cards to this pane: file metadata, source path, and a couple of OS-level actions (Reveal in Explorer, Open Externally). Phase 5 entry — per-type preview cards (texture image, mesh stats, audio duration) come in a follow-up.
