Fix yargs import compatibility for Bun environment

[konard]

🐛 Bug Fix

Fixes #31 - claude-profiles does not work in bun-only environment

🔍 Problem

The issue was that in Bun environments, dynamically loaded CommonJS modules like yargs may be imported as module objects rather than directly as functions. This caused the error:

TypeError: yargs is not a function. (In 'yargs(hideBin(process.argv))', 'yargs' is an instance of Module)

✅ Solution

Added a compatibility layer that handles both cases:

• When yargs is imported as a function (typical Node.js behavior)
• When yargs is imported as a module object (Bun behavior)

Changes made:

1. Renamed the imported module to yargsModule to clearly indicate it's the raw module
2. Added compatibility logic: const yargs = typeof yargsModule === 'function' ? yargsModule : yargsModule.default || yargsModule;
3. Added a test script to verify the fix works correctly

🧪 Testing

• ✅ Created test script that verifies yargs import and usage
• ✅ Confirmed main script works with --help option
• ✅ No breaking changes for existing Node.js environments

📁 Files Changed

• claude-profiles.mjs: Added yargs compatibility layer
• examples/test-yargs-import.mjs: Added test script for verification

This fix maintains backward compatibility while ensuring the tool works correctly in Bun environments.
