domain-decompose

Decompose a domain into bounded contexts, aggregates, entities, value objects, and domain events with ubiquitous-language naming, mapping bounded contexts to candidate microservice boundaries. Use whenever the user wants to decompose a domain, split a system into bounded contexts, identify aggregates / value objects / domain events, define clean domain entities, draw clear boundaries, or plan a monolith-to-microservices breakup. Also use when an already-decomposed domain has evolved and the user wants to update, extend, re-run, or "read existing and update" an existing docs/domain model rather than start over — re-running delta-merges into the existing docs (stable ids, preserves human edits, flags drops) instead of overwriting. Works from a prose domain/requirements description, not existing code. Trigger even when the user never says "DDD", as long as they are carving a domain into boundaries, modelling entities/aggregates/events, or updating a model they already have.
