Summary by cubic

Fixes the broken test environment by building local monorepo packages and skipping API-key integration tests, so local and CI runs no longer fail on import errors or 401s.

• Bug Fixes

  • Build all packages in packages/ before running tests to resolve missing local deps.
  • Skip integration tests that hit external APIs when IGNORE_API_KEY_TESTS=true.

• Migration

  • Running tests locally without API keys: set IGNORE_API_KEY_TESTS=true before the test command.
