Stellar Neovim config optimization

A fast car isn’t built by continuously bolting on new parts. Every so often, it dives into the pit lane, where an entire team tears through a carefully orchestrated routine: worn tires come off, fresh ones go on, adjustments are made, and every movement is designed to send the car back onto the track faster than before. That’s exactly how this rebuild of my Neovim configuration felt. Neovim users have noticed that version 0.12 came with major changes like native LSP configuration and enhancements, improved defaults and diagnostics, native vim.pack plugin manager, experimental UI overhaul (ui2), and broad performance improvements. That was the excuse I needed to sanitize my configuration to eventually come up with this humble blogpost title.
