TouchDesigner-Linux v1.4

What's new

• Complete Python rewrite — replaced the 3340-line bash script with a modular Python codebase (td_lib/)
• Multi-version support — install multiple TouchDesigner versions side-by-side (e.g. 2025 + 2023)
• Interactive version picker — ↑/↓ arrow keys to select TouchDesigner version
• Progress bars — clean download progress for Soda runner and TouchDesigner installers
• Winetricks heartbeat — live progress display during Windows dependency installation
• IDS Peak SDK patching — automatic detection and patching across all installed versions
• .toe file patching — auto-patches NewProject.toe templates with wine_ui_fixes on install, update, and launch
• Versioned shortcuts — separate desktop/application menu entries for each installed version
• --diagnose — new health check command for troubleshooting
• Comprehensive test suite — 171 static tests, multi-distro CI (Ubuntu, Fedora, Arch, openSUSE)
• v1.3 curl one-liner preserved — curl -sSL ... | bash still works

Breaking changes

• Old bash install.sh replaced by Python td-install. The install.sh wrapper still works as the entry point.
