Add DDC Entity

Create a structured entity from: $ARGUMENTS

Steps

1. Check for duplicates — search domain-knowledge/entities/ for existing entities with similar names or IDs
2. Determine entity type — classify as one of: jargon-business, jargon-tech, system, capability, data-model, team, api, persona
3. Determine file path — domain-knowledge/entities/<type>/<kebab-case-id>.md
4. Create the entity file with YAML frontmatter:

   ---
   type: <entity-type>
   id: <kebab-case-id>
   name: <Display Name>
   description: <One-line description>
   status: active
   related_systems: [ids]  # if applicable
   implements_capability: id  # if applicable
   depends_on: [ids]  # if applicable
   ---
   
   # Display Name
   
   ## Overview
   <2-3 sentence description>
   
   ## Details
   <Structured details>
   

5. Cross-reference — if the new entity relates to existing entities, update those entities' frontmatter to include the new relationship
6. Confirm — show the file path and a summary of what was created
