/**
 * Phase 15: Provider Command Tests
 *
 * Tests provider commands for listing providers and models.
 * Provider data is static and doesn't require a running daemon.
 *
 * Tests:
 * - provider --help shows subcommands
 * - provider ls lists all providers
 * - provider ls --json outputs valid JSON
 * - provider ls --quiet outputs provider names only
 * - provider models claude lists claude models
 * - provider models codex lists codex models
 * - provider models opencode lists opencode models
 * - provider models unknown fails with error
 * - provider models --json outputs valid JSON
