Remove unused dependencies

[wycats]

Summary

This PR removes unused dependencies identified through code analysis:

• bin/package.json: Removed globby, pkg-entry-points, spex
• repo-metadata/package.json: Removed fs-extra

Analysis

I analyzed the codebase to verify which dependencies were actually unused vs false positives from the knip tool:

bin directory

• globby, pkg-entry-points, spex - Not imported anywhere in the codebase
• Other reported dependencies (chalk, execa, etc.) - Actually used and kept

repo-metadata directory

• fs-extra - Not used (code uses Node.js built-in fs module instead)
• Other reported dependencies - All actively used in the codebase

Testing

• ✅ pnpm install completes successfully
• ✅ pnpm build completes without errors
• ✅ No functionality changes

This is a small cleanup that reduces the dependency footprint without affecting functionality.
