The tree-wide length check (freed from its BBL/OFL carve-out last commit)
was flagging 21 pre-existing SeeMeCNC files that no vendor index references
and that therefore never load, turning CI red for files with no bearing on
what ships. The rule now only fires on presets a vendor's filament_list
actually references; every .json under the vendor's filament directory is
still parsed through the duplicate-key hook, so that coverage is unchanged.
Also removed a duplicated BAMBU_MAP_PATH definition: update_bambu_filament_ids.py
now imports the constant from assign_filament_ids.py, which it already imports
several other constants from, instead of recomputing the same path independently.
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.
