/vouch-status

Run vouch's kb_status MCP tool and surface the result. Use this when the user asks "what's in our KB?" or before/after a long claim-proposal flow so they can see the proposal count tick up.

Format:

KB at <root>
  claims:     <n>
  sources:    <n>
  entities:   <n>
  pending:    <n>   ← review queue depth
  last audit: <iso8601 timestamp>

If pending > 0, suggest the user run vouch approve <id> (or vouch lint if they want to inspect anything first). Do not propose anything yourself.
