InputToggle 1.2.0

First public release.

Added

• A Windows installer (InputToggle-Setup-<version>.exe, Inno Setup). It
  installs to C:\Program Files\InputToggle, registers the helper task
  \InputToggle\Apply for the installing account, adds the logon entry and
  starts InputToggle as the signed-in, non-elevated user.
• Upgrades stop a running InputToggle of any earlier version the way its
  tray menu's Exit does, so it switches its devices back on before files
  change.
• An uninstaller. It stops InputToggle (devices back on), re-enables anything
  still recorded as switched off, removes the task, the files, the logs and
  the logon entry, and keeps your settings.
• A self-contained release build (PyInstaller): no Python installation is
  needed. Tray and program icons are drawn at build time.
• THIRD-PARTY-NOTICES.txt next to the program, with the licenses of the
  bundled runtime (CPython, Tcl/Tk, mpdecimal, the PyInstaller bootloader).
• --version, and --out <file> for the read-only modes --version,
  --status and --selftest (the release exe has no console).
• An optional desktop shortcut that switches the selected devices off and on
  (installer option).
• build.ps1 and a GitHub Actions workflow that test, build and publish
  releases together with SHA256SUMS.txt.

Changed

• Nothing is pre-selected. On the first start, Settings opens once so you can
  choose the devices.
• "Start with Windows" starts InputToggle.exe, and the app keeps the logon
  entry in line with that setting.
• The tray application refuses to run elevated (the elevated half of a UAC
  split token) and says so.
• --selftest no longer expects particular hardware.
• Messages about a missing helper now say "reinstall InputToggle".

Verify the download with SHA256SUMS.txt (sha256sum -c, or Get-FileHash in PowerShell).
