import_batch.py
================

Import every component found under a source directory into the MIKILAB
library, one subdirectory per component:

    batch_source/
        TPS7A2018PDBVR/
            TPS7A2018PDBVR.kicad_sym
            SOT95P280X145-5N.kicad_mod
            TPS7A2018PDBVR.step
        ESP32-S3-WROOM-1/
            ESP32-S3-WROOM-1.kicad_sym
            ESP32-S3-WROOM-1.kicad_mod

Usage:
    python3 scripts/import_batch.py --source /path/to/batch_source [--category power]

Each subdirectory name is used as the component --name. Exactly one
.kicad_sym is required per subdirectory; a .kicad_mod and a 3D model
(.step/.stp/.wrl/.wrz) are optional, matching import_component.py's
"symbol only / symbol+footprint / symbol+footprint+model" support.

This is a thin loop around import_component's core functions -- no
separate collision/validation logic is reimplemented here, so behaviour
(refuse existing names, dedupe identical footprints, rename real
collisions, regenerate lib tables) is identical to a single
import_component.py run, just repeated per subdirectory. The lib tables
are regenerated once at the end rather than after every component, for
speed.
