What this changes, and why

How it was verified

Checklist

• yarn typecheck and yarn workspace @agentx/engine lint pass
• yarn workspace @agentx/engine test passes
• Changed a response shape covered by src/contract/wire.ts? The contract is updated in this
  same commit
• New or changed mutating route? It validates with validateBody(schema), and its entry is
  deleted from routeBodyValidation.test.ts if it had one
• Schema change? Additive DDL in columnMigrations (sqlite) and the IF NOT EXISTS block
  (pg), with existing ids left byte-identical
• New setting? It gates real behaviour. A control that stores state nothing reads is a bug
