The foundation of the new Temporal CLI experience

This post announces the unification of Temporal's command-line tooling into a single `temporal` CLI. It details the motivation behind this change, stemming from the desire for a single binary and a lighter-weight development experience. The post highlights the engineering challenges of creating a single binary, particularly concerning dependencies like Cassandra and Elasticsearch, and how SQLite emerged as a solution. It also discusses the inspiration from Datadog's Temporalite project and Temporal's subsequent acquisition of ownership. The new CLI integrates Temporalite's capabilities with full support for Advanced Visibility and the next-generation tctl experience, aiming to improve the getting-started experience for both new and existing users.
