Subject: [PATCH] fix(nvim): stop treesitter parser drift from local site
 installs

Force nvim-treesitter to avoid startup parser installs and rely on Nix-provided grammars only, preventing stale ~/.local/share/nvim/site/parser .so files from causing query/parser mismatches (e.g. vim "tab" node errors on ":").
