mp3splt-gtk

• Path: arch/maintained/mp3splt-gtk
• Build failure during the 2026-07-07 “build all packages for x86_64” private-repo release pass. Needs libaudclient>=3, not in this arch/ tree (external-dependency class, see memory/dbmodel-qt4.md). Not fixed as part of this pass.
• 2026-08-02: fixed. Vendored libaudclient from AUR (see memory/libaudclient.md). Built+published cleanly (both mp3splt-gtk and mp3splt-gtk-docs, 0.9.3.1519+r4+g4b48268-3), x86_64 (mp3splt-gtk-docs is an any package, symlinked across every other arch by repo_publish.sh).
