IDE Level Intelligentce LSP: Go-to-Definition, Hover, Diagnostics & Rename | NeoWin Episode 10

Add IDE-level intelligence to your Neovim config with LSP! In Episode 10, we install mason.nvim for language server management, configure pyright for Python, and set up 8 keymaps for go-to-definition, hover docs, find references, rename, code actions, and diagnostic navigation — all without leaving the terminal. Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace.
