desk-exec: init at 1.0.2

[AxerTheAxe]

Hello, I would like to package my program desk-exec.

desk-exec is a robust CLI-based application launcher for Linux. It provides an efficient way to search and execute desktop entries directly from the command line, with support for filtering by program names, substrings, mimetypes, and more. Designed for terminal-focused workflows, it follows the XDG Base Directory Specification, ensuring compatibility across Linux distributions.

I created desk-exec because I couldn't find a CLI tool that met my needs for launching applications based on desktop entries. Existing tools are either GUI-focused or lack the fine-grained filtering capabilities required for power users. This utility fills that gap while remaining lightweight and fast.

Unique Features:

• Seamless integration with the XDG Base Directory Specification.
• Advanced filtering options (name, substring, mimetype, etc.).
• Minimal dependencies, making it suitable for a variety of environments.

I believe desk-exec is general-purpose and lightweight enough to be included in nixpkgs.

This is my first PR so sorry if I get anything wrong. Thanks!
