Adds shove_needed.dsn: one signal layer (no vias), where NET_A routes as a straight wall that boxes NET_C out under greedy ordering. Tests assert the contrast: without shove NET_C is dropped (result still DRC-clean, just incomplete); with shove NET_A is moved aside and both nets connect, the exact has_violation check is clean, endpoints stay on pads, and the result is deterministic. Regression tests confirm shove is a no-op on the simple/ crossing/ripup/kicad boards (same connectivity, DRC-clean, zero shoves). Oracle-gated parity is included (skips when the JAR cannot route the synthetic single-layer board).
