Function writePartialMarker

src/lib/bundle.ts:764–779

* Write ` /.partial` so an agent inspecting the dir can detect * an aborted bundle. The marker is small JSON — the contract is "if * `.partial` exists, do not consume ` ` until the CLI is re-run * and `.partial` disappears." * * We DO NOT clean the `.tmp/` contents on partial — leaving

(
  dir: string,
  err: unknown,
  requestId: string,
  snapshotId: string,
)

 * call clears them.
