backbone-digest 0.8.0

KPI digests — the periodic KPI-email engine: a declarative name-keyed KPI registry other modules extend, per-recipient fenced rendering with declared (never row-count) KPI drops, the anti-spam slowdown ladder, a shared tips carousel, and a daily plain-pull cron whose due-date column is the queue (Odoo digest port)
