/**
 * EnterPlanMode / ExitPlanMode — Vigil-parity planning workflow.
 *
 * The agent enters plan mode to write down a multi-step implementation
 * plan that the user reviews and approves before any tool that mutates
 * state runs. ExitPlanMode is called when the plan is approved.
 *
 * Plans are persisted to <workingDir>/.vigil/plans/<id>.json so the
 * portal can render them and the user can revisit them later.
