Inspect top-level directories and pinpoint which folders consume disk space in bloated repositories.
Identify duplicate files across your workspace using parallel content hashing and calculate wasted space.
Optionally bypass .gitignore and ignore rules to scan every single file in the directory tree.
Uninstall cleanly with ferrum-scan uninstall or -Uninstall script flag with safety prompts.
Inspect commit counts, total contributors, top committers, and recent activity dates automatically.
Export formatted reports to SCAN_REPORT.md or structured JSON for documentation & CI pipelines.
