/**
 * E2E spec for the consolidated Harnesses settings surface + Add-harnesses
 * catalog dialog.
 *
 * Covers:
 *  - Ready preset gets a row in "Your harnesses"; needs-setup preset does NOT
 *  - Needs-setup preset appears in the Add-harnesses catalog with status,
 *    curated description, docs link, and setup action
 *  - Catalog search filters the list
 *  - Toggling install does not reorder rows (stable order)
 *  - Add custom harness via catalog (name+command → save → row appears)
 *  - Advanced disclosure hides ID/args/env/docs/hint until opened
 *  - Edit preserves env vars (round-trip through definitionEnv boundary)
 *  - Same-ID edit replaces entry (no duplicate row)
 *  - Rename removes old row and shows new row
 *  - Delete success removes row; delete failure shows inline error
 *  - PATH badge: custom harness row shows Detected when available
 *  - Preset rows render bundled logos, never initials
 *  - Onboarding navigate: setup-page "More harnesses" click → Settings → Agents (F8)
