feat:programming: Enhance language-specific keybindings and setup

Add language-specific keybindings and configurations for C, Go,
Python, and shell scripting panels. Introduce system utility
function declarations and improve keybinding consistency across
languages. Implement keybindings for debug, format, and static
analysis tools tailored to each programming language, enhancing the
developer experience and workflow efficiency.
