/**
 * Codegen: Python workbench helper source -> generated TS constant.
 *
 * The workbench helper is authored as real, ruff-lintable / pytest-testable
 * Python under `src/workbench/python-helpers/`. The bundler (tsdown) and the
 * tests (vitest) both consume a plain committed `.ts` constant, so we generate
 * `src/workbench/python-helpers.generated.ts` from the `.py` source-of-truth.
 *
 * Run: pnpm --filter @composio/experimental run build:python-helpers
