- overlays/mods/n8n.nix: add passthru.updateScript pointing to ./update.sh
- overlays/mods/update.sh: self-contained updater that fetches the latest
stable n8n-io/n8n release, recomputes both src and pnpmDeps hashes
(src via nix-prefetch-url with --name workaround for the `@` in the tag,
pnpmDeps via the lib.fakeHash mismatch trick)
- .gitea/workflows/nix-update.yml: discover and run overlays/mods/*/update.sh
after the pkgs/ loop; verify step skips overlay/* entries (covered by flake check)
The test suite (tests/n8n-overlay-test.nix) forbids exporting a local n8n
package, so the overlay cannot be exposed via pkgs/n8n/ — the workflow gets
an explicit overlay-discovery block instead.
