Error message

Either `node` or `range` must be provided when reporting an error

What it means

macOS variant of the dev-dir lookup: LAUFEY_DEV_DIR is set, so the `.app` bundle is resolved from the local laufey checkout, but no `.app` bundle for the backend could be located under it.

Solutions

1. Produce the `.app` bundle in the checkout (run laufey's packaging/bundle step) and re-run
2. Verify the expected `.app` path exists under the checkout before launching
3. If dev mode was unintended, unset LAUFEY_DEV_DIR to use the cached/fresh download

const devDir = Deno.env.get('LAUFEY_DEV_DIR');
if (devDir && !await exists(`${devDir}/target/release/laufey.app`)) {
  throw new Error('LAUFEY_DEV_DIR set but no built .app — run laufey\'s packaging step first');
}

When it happens

Trigger: LAUFEY_DEV_DIR pointing at a checkout that was built as plain binaries but whose macOS `.app` bundle was never produced, or was produced in a non-default location.

Common situations: Building laufey with `cargo build` only (no bundling step); stale clone missing the packaging output.
