The v2 migration checklist tells readers to send plan_update with
{ "type": "items", "planId": ..., "entries": [...] }, but $defs/PlanUpdate
requires a plan object (required: ["plan"]). The same guide's Plans section
and docs/protocol/v2/agent-plan.mdx already show the plan wrapper, so the
checklist literal is the odd one out.

Before: the literal fails schema validation with 'plan' is a required property.
After: { "plan": { ... } } validates against $defs/PlanUpdate.

Docs-only change; prettier --check passes. No schema or Rust changes.
