/**
 * Shared web-tree-sitter loader for the Tier-S parser analyzers (Python / HTML /

 * grammar parses identically on every platform; grammars ship as `.wasm` files
 * in `tree-sitter-wasms` (out/tree-sitter-<lang>.wasm).
 *
 * Everything here degrades to `undefined` on any failure (missing dependency,
 * missing grammar, init error) so a caller simply keeps the deterministic regex
 * floor. The runtime is initialised once and parsed grammars are cached.
