Monorepo Cleanup Tool

Build a command-line tool that helps developers clean their monorepo workspace by removing node_modules directories and optionally build artifacts from packages.

Requirements

The tool should provide the following capabilities:

Command-Line Interface

Create a CLI tool with the following commands:

1. clean-all: Remove node_modules from all packages in the workspace
2. clean-scoped: Remove node_modules from packages matching a specified pattern
3. preview: Show what would be cleaned without actually removing anything

Features

• Accept a package name pattern as an argument for the clean-scoped command
• Support a --yes flag to skip confirmation prompts
• Display a list of packages that will be cleaned before proceeding
• Show a summary after cleanup (number of packages cleaned, directories removed)
• Handle cases where node_modules doesn't exist gracefully

Expected Behavior

• The tool should discover all packages in the workspace
• When cleaning specific packages, use pattern matching to filter packages
• Before removing directories, ask for user confirmation unless --yes is provided
• Report which packages were cleaned successfully

Test Cases

• Running the preview command lists all packages and their node_modules directories without removing them @test
• Running clean-scoped with pattern "auth-*" only cleans packages whose names start with "auth-" @test
• Running clean-all removes node_modules from all packages in the workspace @test
