Subject: Cross-platform support: Windows build target and CI release workflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Normalize watcher paths to forward slashes (Windows events use
  backslashes; all sync maps are '/'-keyed), path.delimiter for
  PATH/TEXINPUTS, dirname() instead of '/'-substring splits, bridge log
  in os.tmpdir()
- Platform-aware TeX search paths (TeX Live / MiKTeX on Windows),
  terminal shell default (COMSPEC/powershell), native window frame off
  macOS
- electron-builder: NSIS target + win icon + GitHub publish provider
- GitHub Actions workflow builds the Windows installer on tag push
  (node-pty needs MSVC — cannot cross-compile from macOS) and attaches
  it to the release
