Segmenting Datacloud

This handles the audience and insight layer of Salesforce Data Cloud: creating segments, publishing them, managing calculated insights, and troubleshooting segment SQL. It wraps the sf data360 CLI commands for segment and calculated insight workflows, runs readiness checks before mutating assets, and verifies outcomes with counts or SQL instead of trusting command exits. One smart call: it distinguishes Data Cloud segment SQL from SOQL and reminds you to use joins instead of the opaque member IDs that segment members returns. If you're building audiences or aggregates in Data Cloud, this orchestrates the publish, inspect, and debug cycle. It won't touch upstream harmonization or downstream activation work, which live in sibling skills.
