What changed

TestRunCommandsDoNotLaunchTUI now calls isolateCLIUserState, runs every command from a t.TempDir() working directory, and injects a prepareWorktree stub that records its options and returns an error. After the loop it asserts the stub was called twice (once for worktrees, once for worktree) and that both calls were for the temporary directory. Test-only; no production change.

Why

The test injects only runTUI, so runWithDeps fills everything else with the production dependencies. Bare worktrees and worktree default to worktrees prepare, which ran git worktree add against the repository the tests were running in and locked the new checkout under the real per-user state directory (%LOCALAPPDATA%\zero\worktrees on Windows, ~/.local/state/zero/worktrees on Linux). Every go test ./internal/cli run added two, and nothing released them. A developer box here had accumulated 362 of them since July. #1205's description notes the same leak and says it needs its own PR.

Linked issue

None. Test-only hermeticity fix opened through the internal development process.

Verification

• Checkouts registered with git around one run of the test: the old test goes from 461 to 463 (two new locked task-* entries), and the new one stays at 461. The new test also runs in about 1s instead of 9.5s.
• The whole go test ./... suite on this branch registers nothing new.
• Removing the prepareWorktree stub fails the test, because the stub is then called 0 times instead of 2. Removing the getwd stub fails it because prepare ran for the package directory instead of the temporary one. Neither mutation leaked anything.
• go vet ./internal/cli/ for windows, linux and darwin, gofmt, the release build and smoke, and git diff --check.

Summary by CodeRabbit

• Tests
  • Added coverage for the worktree and worktrees CLI commands, verifying they prepare worktrees in an isolated temporary directory without affecting the developer’s environment.

Walkthrough

The test isolates CLI user state and uses a temporary working directory. It replaces real worktree preparation with a stub and checks that both worktree command spellings invoke it for the temporary directory.

CLI worktree test

Layer / File(s)	Summary
Isolate and verify worktree preparation internal/cli/app_test.go	The test sets isolated CLI user state and a temporary working directory. It records calls to the worktree preparation stub and verifies that both calls use the temporary directory.

Merge readiness

The branch is two commits behind live main (9117d77 vs merge-base 17fcd266). Nothing in the three-dot diff touches internal/cli/app_test.go on those intervening commits, and the PR is mergeable without conflict. Rebasing onto current main before merge is still good hygiene.

Security & Code Health failed on this PR's CI run (govulncheck (linux) reporting stdlib GO-2026-6859 via net/http call chains). The diff is test-only and does not touch any cited packages. The same job passed on current main (9117d77). Treat this as an unrelated or transient CI failure unless the target branch begins failing the same check consistently; it is not introduced by this change.

CodeRabbit's Docstring Coverage warning applies a Python-style docstring gate to Go test edits and is not a repository merge requirement for this project. No action needed for this PR.
