/**
 * Create a companion shares table for an ownable resource. Call this right
 * after defining the parent table.
 *
 * Columns:
 * - `id`              — share row id (generated by the share action)
 * - `resourceId`      — id of the parent resource
 * - `principalType`   — `'user' | 'group' | 'org'`
 * - `principalId`     — email (for user) or org id (for org)
 * - `role`            — `'viewer' | 'commenter' | 'editor' | 'admin'`
 * - `createdBy`       — email of the user who created the share
 * - `createdAt`       — ISO timestamp
 *
 * Uniqueness across `(resource_id, principal_type, principal_id)` is enforced
 * at the action layer via upsert-style logic. A composite DB-level unique
 * index can be added per template if desired — omitted here to keep the
 * factory uses the shared Postgres schema helpers.
