Code Review

This pull request introduces "Growth Mode" to the autobots simulation, enabling organic user growth modeling through persona-driven behaviors and a party pool system to manage Canton party limits. On the backend, it implements a pagination strategy for ledger updates to bypass the 200-element cap on active contract queries. Feedback identifies a potential crash risk when handling opaque ledger offsets as integers and performance bottlenecks caused by full ledger scans on every query. Additionally, corrections are needed for CLI argument parsing to allow zero values, and improvements are suggested for network request reliability and pagination efficiency.
