chore(deps): update minor and patch updates (nuget)

act_runner laedt reusable workflows per git-clone ueber HTTPS. Dieser Pfad
ist auf der Forge seit 2026-08-12 defekt (git upload-pack --stateless-rpc
bricht mit BUG "packfile_uris requires sideband-all" ab). Die Scans liefen
bisher nur ueber eine im Juni gecachte Kopie im Runner.

Der Scan steht jetzt vollstaendig in dieser Datei, der Quellstand kommt als
tar-Archiv statt ueber actions/checkout. Zurueckbauen, sobald git fetch
ueber HTTPS wieder funktioniert.

+# Deliberately NOT calling the reusable workflow in security-workflows:
+# act_runner fetches reusable workflows by cloning them over HTTPS, and git
+# fetch over HTTPS is broken on this Gitea instance since 2026-08-12
+# (`git upload-pack --stateless-rpc` aborts with
+# BUG("packfile_uris requires sideband-all") and dumps core). The runner only
+# kept working because it still had a June copy in its action cache. Inlining
+# removes that dependency entirely.
+#
+# For the same reason the sources are pulled as a tar archive instead of via
+# actions/checkout. Restore the reusable call once the fetch path is fixed.
+#
+# Why one job, not two parallel jobs: act_runner v0.6.1 has a race when two
+# jobs in the same task share a workspace and chown it in parallel.
