Implement three foundational schema features from the design doc: - Tree forking with lineage tracking (migration 022): parent_tree_id, root_tree_id, fork_depth columns with self-referential FKs and composite analytics index - Custom step enhancement: CustomStepSchema with source tracking (ad-hoc, step-library, forked-tree) for backward-compatible JSONB - Session sharing (migration 023): session_shares and session_share_views tables with account-scoped visibility, cryptographic tokens, view tracking, and allow_public_shares account policy Includes 21 new integration tests (9 forking, 12 sharing), SaaS consultant-recommended denormalizations, rate limiting on public share access, and test fixture fix for invite code requirement.
