v4.4.0: stable installers that follow the newest published buildHEADmaster

Adds web/latest.php: a plain-text feed of the newest version with each artifact's filename and SHA-256. The per-release generated installers are replaced by stable web/install.sh and web/install.ps1; both read the feed, pick the newest build, verify it, install per-user and add a launcher. Publishing a new app version no longer regenerates or versions the installers.

publish.sh drops the installer renderer and Python dependency. deploy.sh now also verifies latest.php against the local artifacts and that the served installer scripts match the repository.
