assist sync copies this repo’s slash commands into ~/.claude, but it only ever added them. Rename or delete a command and the old one lingered forever, so the harness kept offering commands that no longer existed. pruneCommands now removes anything in the target directory that assist previously installed and no longer ships, which makes a rename a rename rather than a duplication.

The other change was the session top bar, which had been truncating the ids and item chip to fit the status and toggles on one line. It now lays out so the identity always survives — losing the session id to an ellipsis defeats the point of putting it up there.
