Elegoo: per-product-line roots and filament_ids

Phase 2 of the filament_id cleanup (37 collision groups; one systematic
mistake: every commercial line inherits the material-class @base and its
E<MAT>B00 id). 23 new per-line @base roots with fresh deterministic mints
(no per-line roots existed, contrary to the plan text), 155 inherits
repoints, 23 index entries inserted between the parent @base and the line's
members (load-bearing order), 6 in-place mints on single-member generic
derivatives.

The @base-owning families keep their ids (Elegoo PLA=EPLAB00 etc.); 2 forced
family-atomic re-ids outside collision groups (Elegoo Rapid TPU 95A @EN2
Series/@Elegoo Giga follow their family). Residual 2-family shares
(GPETGB00/GASAB00 with the Centauri -CF lines, pure-template ETPUB00/
EPAHTB00) are printer-disjoint, validator-clean, and frozen in the snapshot.

Verified: config-equivalence gate zero unexpected diffs; extra check exit 0;
--check exit 0; validator -l 2 exit 0; extended -f -v Elegoo exit 0 (was 37
groups / 1332 printer-level errors on the pre-apply copy).
