fix: remove postinstall wrapper dependency

[omribz156]

Summary

• remove the postinstall-postinstall runtime dependency from the published CLI package
• keep the existing package postinstall script as patch-package, so npm still applies the package patches during install without the extra wrapper re-running the script through Yarn/npm

This is aimed at #146. I could not reproduce the published global install failure in a clean Windows temp prefix, but the stack in the issue points at node_modules/postinstall-postinstall/run.js; removing that wrapper keeps the install path simpler while preserving the package's own patch step.

Verification

• yarn build
• npm pack --ignore-scripts --pack-destination ..\artifacts\pack
• npm install --prefix ..\artifacts\npm-prefix-fixed -g ..\artifacts\pack\mondaycom-apps-cli-4.10.8.tgz
• installed package check confirmed postinstall-postinstall is not installed
• ..\artifacts\npm-prefix-fixed\mapps.cmd --version
• git diff --check

I also tried yarn test --runInBand, but one create test failed in my local Windows run while doing a live template clone and comparing spinner output (> vs ✔), so I did not count that as verification for this packaging-only change.

This was implemented with Codex assistance, with the final diff manually reviewed and kept focused.
