Remove the hardcoded release tag and fetch the latest TREK release. Consolidate builds to npm workspaces (shared, client, server), copy client dist into server/public, and install/prune server deps for production. Add libkitinerary dependency and ensure dependencies during upgrade. Implement backup/restore during upgrades and add migration logic that detects the old systemd ExecStart; when present, rewrite trek.service to run the compiled dist via node --require tsconfig-paths/register, add XDG_CACHE_HOME and QT_QPA_PLATFORM env vars, and switch to network-online.target. Installer changes also create data/uploads directories, set additional .env defaults (TZ, LOG_LEVEL, DEFAULT_LANGUAGE, ALLOWED_ORIGINS), and adjust workspace setup steps.
