v1.4.0

AudioClip playback confirmed working

The AudioClip Play/Stop preview (and export) shipped in v1.3.0 has now been
manually verified end-to-end against real AudioClip-bearing AssetBundles - it
was previously untested since no AudioClip-containing file had been available
during development.

A CHANGELOG.md
has also been added, documenting release history since v1.0.0.

Two downloads available

This release has two builds - pick whichever matches what you need:

• AssetStudio.Maui-v1.4.0-macOS.zip - built automatically by GitHub Actions CI.
  Does not include FBX export or AudioClip playback preview, since the proprietary
  Autodesk FBX SDK and FMOD Engine aren't available on GitHub-hosted runners.
• AssetStudio.Maui-v1.4.0-macOS-Universal.zip - built locally with both the FBX SDK
  and FMOD Engine installed, so it includes FBX export and AudioClip playback preview
  on top of everything else. This is the recommended download if you want every feature.

Both are otherwise the same v1.4.0 build (same source, same commit) - "Universal" here
refers to feature completeness, not CPU architecture (both zips already contain universal
arm64 + x86_64 binaries for the native libraries).

See the README's Requirements
section for details on the FBX SDK / FMOD Engine and why they can't be bundled directly in
either zip.

The app is not code-signed with a Developer ID or notarized, so macOS Gatekeeper will block
it on first launch: right-click the app -> Open, or run xattr -cr AssetStudio.Maui.app
before launching.
