ci: install agent CLIs in playwright job + remove env-dependent opencode test assertions

The Playwright E2E tests (archive-tab, terminal-performance) fail because
the CI job doesn't install Codex/OpenCode binaries that the tests need to
create agents. Add the same install step already used in cli-tests.

The 15-provider CLI test still asserts third-party providers are connected
in OpenCode, which is environment-dependent. Remove that assertion and
lower the minimum model count to 1, keeping only deterministic structural
checks (namespacing, required fields, first-party models).
