Add treesitter + auto-pairs/auto-tag-closing to Neovim config

Not part of the original vimrc (no auto-pairs plugin existed there) -
added per request for PyCharm-like brace/quote/HTML-tag auto-closing.

- nvim-treesitter (main branch, the current rewrite) with parsers for
  the languages already covered by the LSP/plugin setup, plus
  highlighting enabled generically via vim.treesitter.start() on
  FileType (a no-op, caught by pcall, for filetypes without a parser).
- nvim-autopairs for bracket/quote auto-closing.
- nvim-ts-autotag (treesitter-based) for HTML/JSX/similar tag
  auto-closing and renaming.
