neovim: overhaul plugin config and keybinds

Remove lsp-zero (replaced with native Neovim 0.11 LSP support),
vim-fugitive, and pyright. Add basedpyright, gitsigns, which-key,
trouble, todo-comments, indent-blankline, and telescope-fzf-native.
Clean up duplicate keybinds and organize under which-key groups.
