fix(ci): force a space-free Windows artifact name to satisfy electron-updater

Symptom — auto-updater on installed v1.4.5 clients was failing:
  "Could not check: Cannot download .../v1.4.5/Tiger-Studio-Manager-Setup-1.4.5.exe, status 404"

Root cause — three different filenames for the same physical .exe:
  • dist/                      → "Tiger Studio Manager Setup 1.4.5.exe" (literal spaces, electron-builder default)
  • Asset on the GitHub Release → "Tiger.Studio.Manager.Setup.1.4.5.exe" (GitHub auto-rewrites spaces → dots on upload)
  • latest.yml (manifest)      → "Tiger-Studio-Manager-Setup-1.4.5.exe" (electron-builder URL-encodes spaces → dashes)

The dashes in latest.yml didn't match the dotted asset name, so the
auto-updater hit 404 every time.

Fix:
  win.artifactName = "Tiger-Studio-Manager-Setup-${version}.${ext}"

This forces the local filename in dist/ to be space-free, so:
  • dist/                      → Tiger-Studio-Manager-Setup-1.4.5.exe
  • Asset on Release           → Tiger-Studio-Manager-Setup-1.4.5.exe (no rewrite, no spaces to fix)
  • latest.yml                 → Tiger-Studio-Manager-Setup-1.4.5.exe (matches)

For the already-shipped v1.4.5 release: latest.yml has been patched
in place via `gh release upload --clobber` so the existing asset
(dotted name) is still discoverable. Users who hit the 404 already
will succeed on the next "Check for updates" since electron-updater
re-fetches latest.yml every time.
