backbone-events 0.5.0

Events core + the sale/booth/crm/sms/desk overlay — registrations under one authoritative seat counter, the sale seam (order-minted registrations, forward-only paid heal, SO-cancel mirror cascade), booth bookings with the DB exclusivity wall, closed-vocabulary lead rules through a host sink port, the dual-channel (mail/sms) self-arming scheduler, and the exact-match desk verb (Odoo event port, core + overlay)
