Place vendored web media libraries in this directory.

Expected filenames:
- video-js.min.css
- video.min.js
- pdf.min.js
- pdf.worker.min.js
- wavesurfer.min.js

Build step behavior:
- `post_build.rs` copies all files from this folder into plugin resources at
  `Contents/Resources/web/` (macOS) or next to `.fmx64` in `web/` (Windows).
- `Inlay_S3_RENDER_MEDIA_HTML` will try loading local `file://.../web/*` assets first,
  then fall back to CDN URLs if local files are missing.
