build-plugin

Build a new agentz marketplace plugin from a confirmed intent brief, scaffolding the Agent Plugins 1.0 layout and authoring its skill, using HVE Core's hve-builder when it's installed. Use when the user says "create a plugin", "new plugin", "scaffold a skill for the marketplace", or after research-catalog returns a "new" verdict. This is phase 3 of 4 (Analyse, Research, Build, Validate). Do not use to edit an existing plugin's logic or to install plugins.
