P2 Badge Restore fallback folding for non-Tree-sitter filetypes

When a buffer has no Tree-sitter parser or vim.treesitter.start() fails, this global foldmethod=expr still leaves foldexpr as vim.treesitter.foldexpr(), which returns 0 without a parser, so those files have no folds at all. The repo only installs parsers for a limited set of languages in lua/config/treesitter.lua, and its FileType fallback only enables syntax on; it does not switch folding back from expr, so opening unsupported filetypes such as YAML/JSON or any parser install failure regresses from the previous indent-based folding to no usable folds.
