V2.10.41 - align program name to cubecloud-agent-desktop

Two-file change:
- electron-builder.yml: productName Agent Desktop -> cubecloud-agent-desktop
- cubecloud-desktop/.github/workflows/release.yml: release title
  'Agent Desktop v\' -> 'cubecloud-agent-desktop v\'

The user-facing program name is now cubecloud-agent-desktop.
The internal executable and file names (cubecloud-desktop.exe,
cubecloud-desktop-0.6.0-*.exe) are unchanged because package.json
'name' and win.executableName are out of scope for this commit.

Verified: electron-builder produces an installer that installs as
cubecloud-agent-desktop in Windows Programs and Features.
