fix(nvim): use canonical solarized + actually install treesitter parsers

- plugins.lua: replace maxmx03/solarized.nvim with altercation/vim-colors-solarized
  (the same colorscheme vim already uses via Vundle). Run with termguicolors=false
  so the terminal's solarized 16-color palette is used directly. solarized.nvim's
  truecolor reinterpretation was leaning on magenta/violet/cyan accents and
  reading as "pink/purple/teal" instead of classic solarized.
- treesitter.lua: enable `build = ":TSUpdate"` so parsers actually compile
  on plugin install/update. Without it, ensure_installed was a no-op and
  treesitter highlighting (incl. markdown code-block injection) silently
  did nothing.
- packages.txt: add tree-sitter-cli — required by nvim-treesitter to build
  parsers; the brew tree-sitter formula was split into lib-only.
