fix: Stop running unnecessary npm install in engines tests#12081
Merged
Conversation
The engines tests only use `turbo build --dry=json` which plans the task graph without executing tasks. Turbo only needs package.json files and the lockfile for this, not node_modules. Passing install: true caused intermittent failures on Windows CI when npm install --offline failed due to corepack/symlink issues. Also capture stderr in run_cmd so future install failures include diagnostic output instead of just an exit code.
