"""
Fix nsSplashPNG repo:
1. Rimuove dal tracking i file di build MSBuild in src/ (artifacts + DLL grezze)
2. Sposta le DLL pre-built in dist/ (struttura canonica)
3. Aggiunge regole .gitignore per escludere le cartelle Release in src/
4. Aggiunge dist/ al tracking (con DLL binarie)
5. Commit + push Gitea + push GitHub
