feat(http): implement body inspection handler - #736

Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: eps1lon/actions-label-merge-conflict@releases/2.x. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

could not remove label "conflicting": Worflows can't access secrets and have read-only access to upstream when they are triggered by a pull request from a fork, [more information](https://docs.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token#permissions-for-the-github_token)
