Review a data model domain to assess relationships, rollups, and index candidacy.

Wraps agents/data-model-reviewer/AGENT.md. Reviews relationships, rollups, External ID coverage, growth forecast, and index candidacy for a root object + its related objects.

Step 1 — Collect inputs

1. Root object API name?  (e.g. Opportunity)
2. Target org alias?
3. Include related objects? (Optional — default: infer from EntityDefinition relationships)

Step 2 — Load the agent

Read agents/data-model-reviewer/AGENT.md + mandatory reads.

Step 3 — Execute the plan

Build domain graph, score relationships, rollup analysis, External ID coverage, growth forecast, index candidacy, emit.

Step 4 — Deliver the output

Summary, domain graph (ASCII), findings, rollup analysis, growth forecast, index recommendations, Process Observations, citations.

Step 5 — Recommend follow-ups

/design-object for new objects suggested by the review
/analyze-field-impact for External ID rollout
/audit-sharing if cascade behavior is unclear

What this command does NOT do

Does not modify relationships or deploy anything.
Does not design new objects (suggests /design-object).
Does not analyze sharing cascading (suggests /audit-sharing).
