Layer-Smart-Join entfernt — nie verwendet, auto Phase 2 macht's

- Alt+Click bypass im Cluster-Volume-Select-Handler raus.
- _layer_join_attempt + dJoin-Detection in smart_join.py raus.

Phase 2 automatic handling deckt die Use-Cases ab. Falls Manual-Layer-
Merge spaeter doch noetig: commit 118bc51 hat den Code als Referenz.
