fix(security): resolve high-severity dependency vulnerabilities

[Killerjunior]

Summary

Updated transitive dependencies with high-severity vulnerabilities (such as axios, ws, form-data, js-yaml, and @babel/core) to secure, patched versions.

• Added overrides to package.json for npm users.
• Created pnpm-workspace.yaml to configure overrides for pnpm v11+ (as pnpm v11 no longer supports the overrides field inside package.json).
• Regenerated pnpm-lock.yaml and package-lock.json with secure dependency versions.

Closes #646
