Research direction

Read the five named test files under pkg/cli and compare their os.Chdir cleanup patterns with existing t.Chdir call sites. Replace the manual directory changes with t.Chdir, then run the relevant pkg/cli tests. Done when the tests pass and the listed files no longer use the manual os.Chdir/deferred restore pattern.

Description

Five pkg/cli test files mix manual os.Chdir(...) / defer os.Chdir(originalDir) with t.Parallel() in the same package: commands_test.go (os.Chdir at lines 100-101/350, t.Parallel() at lines 273/333), list_workflows_command_test.go, add_no_args_test.go, git_test.go, and forecast_test.go — live-verified today. Since os.Chdir changes the process-wide working directory, any test using it is unsafe to run concurrently with sibling tests that assume a stable cwd. This is a latent race today (not necessarily currently triggered, depending on which tests actually run in parallel), but it's fragile to future test additions in the same files.

Expected Impact

Removes a latent test-flakiness source. t.Chdir (stdlib, Go 1.24+) auto-restores the working directory on cleanup and is documented by the testing package as incompatible with t.Parallel() on the same test, making the hazard impossible to reintroduce by accident.

Suggested Fix

Replace the os.Chdir(...) / defer os.Chdir(original) pairs with t.Chdir(...) in the 5 files listed above. The migration path is already proven in this repo — 33 existing call sites already use t.Chdir.

Code Region: pkg/cli/commands_test.go, pkg/cli/list_workflows_command_test.go, pkg/cli/add_no_args_test.go, pkg/cli/git_test.go, pkg/cli/forecast_test.go
