v0.46.0

• Context graph moves from gated implementation to a broader GA-ready surface: entity dedup now uses birth gates, structural provenance tiers, embedding/adjudication passes, connector-aware hierarchy, task/commitment/decision/feature/work-cycle sub-entities, and a Your Org review surface for inspecting and correcting product/project/team structure.
• Summariser configuration is now shared across tenant admins, with org-admin aggregation so admins can see and manage all summariser routes instead of only their own local config.
• Managed member invites now support email-only registration while requiring tenant-scoped tokens for managed member registration, preserving the email-first identity flow without treating WhatsApp as an invite-delivery channel.
