Adds batch authoring tools that collapse the dozens of round-trips needed to
stand up a schematic into a handful: batch_add_components,
batch_edit_schematic_components, replace_schematic_component,
batch_add_no_connects, batch_connect, and batch_add_and_connect (place a set of
parts and wire them in one call). These reuse the existing single-item handlers
internally, so behavior matches exactly.
- python/commands/schematic_batch.py: SchematicBatchCommands(iface)
- python/commands/schematic_text_utils.py: shared .kicad_sch text helpers
- src/tools/schematic-batch.ts + registry 'schematic_batch' category
- python/kicad_interface.py: import + instantiate + dispatch routes
- tests/test_schematic_batch.py: 13 unit tests
Note: schematic_text_utils.py is also shipped by the field-placement and
hierarchy PRs; if those merge first, drop the duplicate copy on rebase.
