Subject: [PATCH] feat: remove hard dependency on `nvim-treesitter`

Remove hard dependency on `nvim-treesitter` for two reasons:

1. `vim.treesitter.get_parser` has been in Neovim core for 4 years.
2. nvim-treesitter's future focus will be on parser installation and
   query aggregation only.

Use Neovim's built-in TreeSitter API instead.

Closes #70
