⚡ Bolt: Optimize cidata ingest directory traversal

[WHYCRASH]

💡 What: Removed os.system("chown -R ...") and integrated native Python os.lchown directly into the existing os.walk loop inside cidata_ingest.py.

🎯 Why: Shelling out to chown creates an unnecessary subprocess fork and forces a redundant full-tree directory traversal. By combining the operations into the existing native Python file loop, we significantly reduce execution time and IO load during secrets ingestion.

📊 Impact: Eliminates one subprocess spawn and halves the number of directory tree traversals for the /target/home/shane directory. Improves cross-platform stability and avoids symlink vulnerabilities by utilizing os.lchown().

🔬 Measurement: Review execution time of the cidata_ingest.py script. The time spent modifying files should be noticeably reduced, specifically eliminating the penalty of the os.system invocation.
