scripts/update_bambu_filament_ids.py derives resources/printers/bambu_filament_ids.json
from BambuStudio's own shipped BBL bundle (cloned from upstream, or read from a local
checkout via --bambustudio-dir), pairing each Bambu catalog id with the Orca filament_id
we already ship for that product where we ship one, else a freshly generated one. Nothing
reads the map yet; later work uses it to translate ids at the Bambu printer boundary.
