Why: Preserve a single Dev entry and independent repository ownership while allowing active feature branches to migrate without losing source or Git state. Evidence: SELF 29 real Git/Go workspace tests and ordinary component evidence/lock tests passed; detailed RED/GREEN runs are recorded by make evidence in the task card. Impact: Add fixed cloning, selected-version baselines, development overlays, npm source resolution, and independently preserved legacy snapshots. No other active worktree is modified.
