TeXmacs Upsilon, latest builds

The latest builds of TeXmacs Upsilon, an enhanced and bleeding-edge
version of GNU TeXmacs with experimental features, from the branch
upsilon_texmacs, with the S7 Scheme interpreter. Each file is
replaced at each build of its platform, and its label names the
commit it was built from (the macOS files: commit ace1de5, 2026-10-19). The tag
upsilon-latest does not follow the builds. The list of the
files, with what each one is: https://mgubi.github.io/texmacs/

• macOS (Apple silicon and Intel, macOS 13 or later):
  TeXmacs-*-cocoa-universal.dmg, the native interface (Cocoa),
  see src/docs/ns-port.md;
  TeXmacs-*-vue-universal.dmg, the Vue interface, drawn by the
  GPU, see vue-graphics-stack.md;
  texmacs-qt-macos-arm64.zip, Qt 6, Apple silicon only.
  Signed ad hoc and not notarized: macOS refuses to open them the
  first time. Open the application from its context menu (Open),
  or allow it in System Settings > Privacy & Security, or remove
  the quarantine: xattr -dr com.apple.quarantine /Applications/TeXmacs.app
• Linux (x86_64, built on Ubuntu 24.04):
  texmacs-linux-x86_64.tar.gz (Qt 6) and
  texmacs-vue-linux-x86_64.tar.gz (Vue): unpack, and run
  TEXMACS_PATH=$PWD/TeXmacs TeXmacs/bin/texmacs in the folder of
  the archive. The Qt build uses the Qt 6 of the system (Ubuntu:
  sudo apt install libqt6svg6 qt6-qpa-plugins).
• Windows (x86_64): texmacs-windows-x86_64.zip (Qt 6) and
  texmacs-vue-windows-x86_64.zip (Vue): unpack, and run
  TeXmacs-Windows\bin\texmacs.exe.

The macOS files were built by this run.
