/**
 * The floating workspace is a directory the user points Orca at, with no repo, worktree or folder
 * row behind it. Anything that resolves a workspace to a filesystem location needs an answer for
 * it, so this mints the same synthetic `Worktree` shape folder workspaces use.
 *
 * Its id stays the sentinel constant: the session journal and every status subject are keyed by
 * workspace id, so inventing a second identity here would split one workspace into two.
 *
 * Minting and recognising it live together so the two cannot drift.
