Subject: [PATCH] fix: dead code cleanup, missing MIME types, partial download
 leak
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- formatSpeed had identical branches in its ternary — simplified
- file server was missing MIME types for avif, flac, m4a, mov, ico so
  those files got served as application/octet-stream
- removed unreachable guard in parseObjectPositionAxis
- partial downloads weren't cleaned up on failure so the next call would
  find and use the corrupted file — now removes partials in catch block
- added description to @hyperframes/core package.json
