`gitea-runner exec --no-skip-checkout` panics with a nil pointer dereference on any job that calls a local reusable workflow (`uses: ./.gitea/workflows/x.yml`).
Fetching a local reusable workflow from the instance was gated on `NoSkipCheckout`, but it reads the repository and SHA from the task's preset context, which only the daemon has. `exec` always has the workflow on disk, so the fetch is now gated on the preset instead, and `--no-skip-checkout` only governs checkout again. Daemon behavior is unchanged.
The `exec` e2e test now also runs the existing reusable caller/callee pair with `--no-skip-checkout`.
