Epic: Serverless Workflow Editor Post MVP Planning

[lornakelly]

Description

Define and prioritise the editor's post-MVP direction. This is a planning epic, not a feature epic. It closes once direction is agreed and work is broken down.

Post-MVP feature work lands as separate epics informed by its output.

Motivation

MVP delivers read-only visualisation; we need an agreed, validated direction for what comes next before committing effort to feature work.
