Make the sensing loop durable and pin the reserve to Scaleway

The weekday brief only counts when the file is on origin/main. Hub
events without git objects are failures. The open-weight SoT moves
from the VAULT 850 GiB quota to a dedicated Scaleway bucket (One Zone
IA for R, Glacier for S) so V4-Flash and K3 are economically in-scope.

Catalogs the real DeepSeek-V4-Flash-0731 (MIT ~167 GiB MoE, not 12B)
and nominates Qwen3.8-27B. Bucket create remains FI-WP-0004-T08.
