shangdi178/dsh-versions

Version manager for the dsh host in a settings section of its own: shows the installed version against npm dist-tags, checks for updates, and installs, upgrades, downgrades or reinstalls any published version with a pre-upgrade local snapshot, failure rollback, snapshot-based rollback and an upgrade history. Before a cross-minor install it compares the @deepseek-ai/dsh-settings exports of the target release with the named imports of installed plugins to flag those that would stop loading, and it can apply or remove reversible compat shims that port removed legacy APIs back into framework files. Upgrade, restore and restart engines are Windows-only; version listing and checks work on every platform.
