juspay/nixos-unified-template

AI Summary: Integrate the Vertex project (https://github.com/juspay/vertex) into the existing NixOS-unified template. This likely involves adding Vertex as a dependency within the template's configuration files, potentially updating relevant modules (home, darwin, nixos) to utilize Vertex's functionalities, and ensuring compatibility across different platforms supported by the template.

AI Summary: Create a home-manager launchd module for macOS to persistently set ulimit -s across reboots and terminal sessions. The module should be disabled by default in the main template but enabled in a separate configuration (nixone). This addresses issues with ulimit settings not persisting and simplifies setup for users.
