chore(baseline): make prepush/weekly, scanner fix for git worktrees

Update the Test & Security Baseline from cj/security-baseline (364d756):
- make prepush runs only the checks the diff needs (scripts/security/changed_scope.py)
- make weekly = check + trivy-fs, run by the weekly cron on cj-ki
- in git worktrees gitleaks scanned 0 commits and Semgrep ignored .gitignore (.next/); fixed

+Aufruf (aus dem Repo-Root, so wie das Makefile es tut):
+  changed_scope.py targets [BASE]   make-Ziele für `make prepush`, eine Zeile
+  changed_scope.py files   [BASE]   geänderte, noch vorhandene Dateien (für `make sast-diff`)
+  changed_scope.py range   [BASE]   Commit-Bereich für gitleaks, leer = keine Basis gefunden
+  changed_scope.py explain [BASE]   Begründung für Menschen
+
+BASE ist die Git-Referenz, gegen die verglichen wird. Ohne BASE: Upstream des Branches, sonst
+origin/HEAD, origin/main, origin/master, main, master. Findet sich keine Basis, wird alles
+geprüft (sicherer Standard).
+
+Geprüft wird der Unterschied zwischen Basis und Arbeitsverzeichnis: die Commits seit der Basis
+plus noch nicht committete und neue Dateien.
+
+Einteilung (Reihenfolge zählt, erste passende Regel gewinnt):
+  Werkzeug    Makefile, baseline.mk, Semgrep-Regeln, Mutationen, pre-commit, CI  -> volles check
+  Abhängigk.  requirements*, pyproject, package*.json, Lockfiles               -> lint test audit
+  ohne Code   Doku, Bilder                                                     -> nur Secrets
