docs(dv2): sweep the retired clothing/footwear storyline out of DV2 docs (C1) (#142)

architecture.md and schema_dv2.md still described the DV2 demo as a
clothing/footwear retailer and attributed the demo branch distribution to
X5 Retail Hero. Both predate the kitchen-appliance own-brand legend fixed
in domain.md (A1) and the B1 generator rebuild, which retired the
40/25/15/10/10 split (order count is now msk-heavy since all FBS/D2C
fulfils from the central warehouse). Branch role descriptions in
architecture.md are aligned with domain.md's footprint table. Real X5
Retail Hero Kaggle-dataset attribution (the loader that actually ingests
45.8M real rows) is left in place where it documents genuine technical
provenance, not business legend, per domain.md §5.4.
