/**
 * Staged-operation params for create_recurring_schedule /
 * update_recurring_schedule. Both the MCP staging tool and the commit
 * executor validate against these, so a tampered pending_operations row is
 * rejected at the commit boundary with the same rules the staging tool
 * enforced (mirrors UpdateCustomerParamsSchema).
 *
 * The field rules live in lib/api/schemas.ts (shared with the cookie-session
 * routes); this module only adds the staged-params envelope.
