gsxdsm da4e4bca44 FN-9053: prevent workspace acquisition from persisting singular worktrees

Keep workspace tasks classified as multi-repository throughout sub-repository worktree acquisition.

- Suppress singular worktree and branch persistence for workspace sub-repo acquisition.
- Preserve the single-repository persistence contract and add regression coverage for acquisition failures.
- Document the workspace acquisition-state invariant and add a patch changeset.
