Subject: [PATCH] statusline-command.sh: Effizienz und Korrektheit verbessern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Alle 7 jq-Aufrufe zu einem einzigen zusammengefasst (Process Substitution + read)
- Zwei separate awk-Aufrufe zur Kostenformatierung auf einen reduziert
- Fehlerhafte if-Bedingung für git-Branch korrigiert (falsche Operator-Präzedenz)
- Unnötige Kommentare für offensichtlichen Code entfernt
