Neovim Configuration

A minimal, fast neovim configuration built for Neovim ≥0.12 (currently nightly) using vim.pack for plugin management.

Overview

This config uses Neovim's built-in package manager (vim.pack) instead of external plugin managers. It provides a complete development environment with LSP support, fuzzy finding, terminal integration, testing/debugging, and formatting capabilities.
