"""
Batch schematic authoring commands.

Tools that place / edit / connect many things in one call to avoid per-item round-trips:
  - batch_add_components:            add many components at once
  - batch_edit_schematic_components: edit many components (value/footprint/reference/...)
  - replace_schematic_component:     swap a symbol, preserving position and field values
  - batch_add_no_connects:           add no-connect (X) flags to many pins
  - batch_connect:                   place net labels on many pins (with facing-label wiring)
  - batch_add_and_connect:           place components and wire their nets in one call

The command class is constructed with a reference to the KiCADInterface so it can reuse
existing single-item handlers (add/edit/get_schematic_component), the footprint library,
and the hierarchical-instance fixer when present.
