/**
 * Phase A/B polish verification — boot skip + spawn-agent flow.
 *
 * Covers:
 *   H-01 (QW-3): BootScreen shows on first visit, skipped on subsequent visits.
 *   H-02 (P35):  SpawnAgentDialog empty-state branches correctly:
 *                - no keys configured  → Settings → Vault CTA with Key icon
 *                - keys configured but no models → retry CTA
 *                - models present     → model chips rendered
 *   H-03 (P36):  Dock spawn-agent icon click opens SpawnAgentDialog.
 *
 * Run: npx playwright test tests/e2e/spawn-agent-flow.spec.ts --reporter=list

 * mounts immediately with the power-tier dock (which includes the
