/**
 * Verifies the unified CLI-flags feature on agent profiles:
 *
 * - The profile editor renders a "Agent CLI flags" section.
 * - Users can add a custom flag via the form, save, and reload; the flag
 *   persists in the DB (assert via the PATCH round-trip).
 * - Toggling a flag off persists across save/reload.
 * - Removing a flag persists across save/reload.
 *
 * Full argv-assembly (tokenisation + launch path) is covered by
 * backend unit tests in apps/backend/internal/agent/lifecycle — we don't
 * exercise a full task launch here because that's both slow and redundant.
