/**
 * Network Membership Graph State.
 * Handles CRUD operations for network memberships (index_members table).
 *
 * ## Membership authority policy
 *
 * - `create` / self-join: allowed only when `joinPolicy: 'anyone'`.
 * - `create` / invite (targetUserId ≠ userId): caller must be a member;
 *   for `invite_only` networks, caller must also be the owner.
 * - `delete`: owner-only; the owner themselves cannot be removed via this path
 *   (delete the network instead).
 * - `read`: caller must be a member of the network to list its members.
 *
 * Flow:
 * START → routerNode → {addMemberNode | listMembersNode | removeMemberNode} → END
 *
 * IND-546: canonical home — previously network/membership/membership.state.ts.
