Disable globalSetup/globalTeardown in generated Jest configs
Projects often use globalSetup to start infrastructure like Docker containers, databases, or test servers. These are needed for integration tests but not for Codeflash-generated unit tests. When globalSetup fails (e.g., Docker not available), all tests fail with: ``` Error: Jest: Got error running globalSetup - globalSetup.ts reason: Command failed: docker context ls --format json /bin/sh: 1: docker: not found ``` **Root Cause:** Both _create_codeflash_jest_config() and _create_runtime_jest_config() spread the original config without explicitly disabling globalSetup and globalTeardown. This causes generated unit tests to inherit heavyweight integration test setup. **Fix:** Explicitly set globalSetup: undefined and globalTeardown: undefined in both: 1. Codeflash config (for ESM package compatibility) 2. Runtime config (for test roots configuration) Unit tests don't need global setup/teardown - they test isolated functions with mocked dependencies. **Testing:** - ✅ All 6 existing globalSetup tests now pass (were failing before) - ✅ All 34 test_runner tests pass - ✅ Linter passes **Impact:** - Fixes trace ID 4760967c and likely many others - Enables optimization of functions in projects with Docker-dependent globalSetup - Common in projects using testcontainers, database fixtures, or API mocking Fixes issue discovered in budibase optimization run where globalSetup.ts requires Docker to start CouchDB testcontainers.
