18 * esbuild the entrypoint into a single tree-shaken `bundle.mjs` (no node_modules), tarred for ADD.
19 * Returns {dfCpTarStr, dockerPathsA, tarSpec} so it drops into getDockerBaseStr as a swap for the
20 * multi-GB node_modules layer. `jiti` stays external (an eslint dynamic import the cronjob never
21 * invokes at runtime). Bundle is built on the dev PC, so no in-cluster/kaniko special-casing is
22 * needed — the pre-built tar is just ADD'd.
