#Release 1.3.6
New features: MediaType enum, centralized detectMediaType() with caching, and remote URL media detection via HTTP headers
Bug fixes:
#22 — keyboard navigation no longer hijacks arrow keys globally (file rename, sidebar, contentEditable)
#22 — slider properly deactivates when clicking outside
Local file rendering regression from the merged PR (resource path query string breaking regex detection)
Technical changes: consolidated type detection, async thumbnails, scoped keyboard handling
