// IMPORTANT: __qwen_filename / __qwen_dirname always resolve to this shim's
// chunk file — i.e. dist/chunks/ in a built bundle, NOT the directory of any
// source file that uses bare __dirname / __filename. esbuild's `define`
// rewrites all free references in source code to these symbols, so to get a
// per-file path you MUST declare a local shadow at the top of your module:
//   const __filename = fileURLToPath(import.meta.url);
//   const __dirname = path.dirname(__filename);
// Even with a local shadow, under code-splitting the path can still point to
// dist/chunks/ rather than the source dir — sibling-asset lookups (vendor/,
// bundled/, locales/) must strip a trailing `chunks` segment. See
// skill-manager.ts / ripgrepUtils.ts / i18n/index.ts for the pattern.
