Proposal:

• Refactored test/command-publish.test.js to properly manage and sanitize process exit listeners.

Changes:

• Added a beforeEach hook to store the state of active process.listeners('exit') before each test execution.
• Added an afterEach hook to purge any orphan process exit listeners registered by proxyquire sub-dependencies during the test run.

Why is this needed?

• Some sub-dependencies mocked via proxyquire were registering persistent exit listeners on the main process without removing them. This could leak memory and pollute the Node.js process environment, potentially disrupting proper process signaling, child process management, or Inter-Process Communication (IPC) boundaries during test orchestration in strict CI pipelines.

This PR should resolve this error CI ( in Nodejs v24.18.0 ):
